**The relationship between Beta Werewolves Erica Reyes and Isaac Lahey**.

Erica and Isaac had pretty much in common prior to meeting newly ascended Alpha Werewolf Derek Hale—Isaac was lonely and abused by his father in all ways, both physically and psychologically, with his worst punishment being spending many hours locked in a freezer in the basement, which made him develop a case of claustrophobia, while Erica suffered from a severe case of epilepsy since childhood and was bullied by fellow high school students because of it.

However, their lives changed when they met Derek and were given the Bite, with Erica becoming much more attractive following her transformation. They instantly became loyal to their new Alpha and helped him recruit one last Beta, Vernon Boyd, with whom Erica seemed to develop a romantic relationship.

Throughout their time in the pack, Erica and Isaac were sent together to accomplish several of Derek's orders and tasks: including testing Lydia Martin with Kanima Venom to verify if she was the Kanima, breaking into the McCall House to overpower Scott McCall, Stiles Stilinski and Allison Argent and murder Lydia, and distracting and sedating Jackson Whittemore, who had indeed become the Kanima.

In time, Boyd and Erica realized that they would not survive the threats of the Kanima and the Argent Hunters in Beacon Hills and left the Hale Pack to search for another one somewhere safer, inviting Isaac to come with them but Isaac preferred to remain in their hometown to help Derek and Scott battle against Gerard Argent and free Jackson from Gerard's control after his first master, Matt Daehler, was killed.

Boyd and Erica were revealed to have been caught by the Alpha Pack and locked in the abandoned First National Bank's vault for over three months. Unbeknownst to Isaac, Derek or anyone else of the Beacon Hills packs, Erica faced off with Kali in a desperate attempt to escape from the vault, only to lose both the fight and her life at the hands of the Alpha. Isaac broke into the bank sometime later and realized it was there where Deucalion and his subordinate Alphas were holding his packmates hostage, but he was found, captured and tortured by the Alphas before having his memories of the bank wiped from his mind. He was eventually rescued by mercenary Braeden and found by Derek and Scott.

In order to get his repressed memories back, Isaac was submerged in cold water and informed his friends that he had briefly seen Boyd and Erica in the vault of First National Bank. He also divulged (though unknowningly) that the Alphas had locked him in a closet, where he found what appeared to be Erica's dead body, though he failed to realized that the other Werewolf with Boyd was Derek's long-lost sister Cora Hale. Isaac and the others received the news that Erica was truly dead when Derek found Erica's lifeless body in the supply closet of the bank. Isaac lamented Erica's death and held a grudge against all the Alpha Pack members, particularly the twins Ethan and Aiden, for her loss.

## Throughout Teen Wolf

* Season 2
* Season 3

In *Ice Pick*, Erica and Isaac joined Derek at the Beacon Hills Ice Rink, where Derek planned to bite and turn Vernon Boyd. They were then confronted by Scott McCall, who disagreed with Derek's insistence on turning more Werewolves and who believed Boyd would be putting himself in more danger by consenting to the bite as a result of the threats from the Argent Hunters and the Kanima.

Derek, offended by Scott's assessment that Boyd "could do better" than him in terms of friendship, called to Erica and Isaac to give Boyd and Scott their opinions on how their lives are now that they've been turned. Erica said the experience was "in a word? Transformative," and Isaac said his life was pretty great, save for the fact that he was currently a fugitive due to being wrongly accused of killing his father.

With a look from Derek, Erica and Isaac got into position to start to fight Scott, with Scott pointing out that it wasn't exactly a fair fight. Derek, thinking he meant the fact that it was two-versus-one and Scott was clearly outnumbered, encouraged him to go home, but Scott meant that it was unfair to the newly turned Werewolves before engaging in physical combat with them. As Scott had predicted, the fight ended quickly with both Isaac and Erica knocked out and slid over to where Derek was standing.

In *Abomination*, Erica and Isaac were involved with training at the Railway Depot where the Hale Pack was currently living while Boyd watched, with Isaac continuing to use the same moves over and over again as he tried to overpower Derek and failed. When Derek, exasperated, asked if anyone wanted to try something that *wasn't* predictable, Erica rushed over, leaped onto Derek, and kissed him. Though Derek indulged her for a moment, he eventually threw her off of him and toward where Isaac had been thrown to the floor earlier, wiping his mouth off before admonishing her not to try that again.

Erica, assuming Derek was looking down on her, asked if it was because she was a Beta, but Derek retorted that it was actually because he had someone else in mind for her. Isaac impatiently asked if this meant they were done, since he had "about a hundred bones" that needed some time to heal, leading Derek to walk over and break his forearm and stated that it was now a hundred and one.

Irritated by the fact that the Betas weren't taking him seriously, Derek asked them if they thought he was trying to teach them to fight before correcting them and stating that he was trying to teach them how to *survive.* Isaac, gingerly cradling his injured arm in his uninjured one, asked why, if the Argents wanted them dead, had they not struck them by now and wondered what they were waiting for, but though Derek admitted he did not know, what he did know was that they were planning *something*.

He then reminded Isaac that he knew that the Argents weren't their only problem, adding that he was pretty sure whatever killed Isaac's father had killed someone else the night before. Derek turned to walk out of the Railway Depot as he summarized that until they figured out what the creature was, Erica, Isaac, and Boyd needed to learn everything Derek could teach them, and as quickly as Derek could teach it to them.

In *Venomous*,

In *Restraint*,

In *Raving*,

In *Party Guessed*,

In *Battlefield*, Boyd and Erica became terrified of the Argents' plan to kill all Werewolves in California and went to the Hale House to inform Derek that they were leaving Beacon Hills to search for another pack somewhere far away from the Hunters. Derek attempted to convince them to remain in his pack because it was the only way to survive the dangers out there, only for them to insist that they had their minds made up and left, with Derek not doing anything to stop them.

Meanwhile, Isaac went to Alan Deaton's animal clinic. After learning that he could siphon the pain from other being with Deaton and Scott's assistance, Isaac informed Scott that Boyd and Erica were going to leave Beacon Hills that night and asked Scott for his advice because he seemed to be the one who always did the right thing, only for Scott to admit that most of the time, he had no idea of what he was doing. He went to reveal his reason for staying in Beacon Hills—he had to protect the people he cared about from Gerard Argent and save their teammate Jackson from Gerard's clutches.

This seemed to touch Isaac, who sadly replied that he was the "lucky" one because he did not have anyone that needed him, following the deaths of his mother, brother and, most recently, his father, leading him to think that he was going to accept Boyd and Erica's invitation to go with them. He wished Scott good luck for the game, only for Scott to claim that he was not going to play, either. He argued that he ad much more important things to think of than a "meaningless" game. Isaac went on to tell Scott that while he skipped lacrosse practice last week, Jackson was there as if nothing had happened and that he would be playing in the game.

Despite Isaac's earlier claims that he would be going with Boyd and Erica, he showed up at the game to help Scott in preventing Jackson from murdering someone in the field under Gerard's orders. Unbeknownst to Isaac or anyone else but Stiles, Boyd and Erica were captured by Allison and Chris before being brought to the Argent House to be interrogated. Argent, who had realized that his father Gerard was the real threat, realized what he was doing was wrong and freed the two Betas hours later. In the woods, Erica and Boyd were once again captured by the newly arrived Alpha Pack.

In *Tattoo*, at the end of the episode, Derek revealed to Scott and Stiles that he, Isaac, and Peter had been searching for Boyd and Erica for the last four months upon learning that they had been captured by the Alpha Pack.

In *Chaos Rising*, Peter performed the Alpha Werewolf Memory Manipulation ritual on Isaac to uncover if he had found Boyd and Erica while breaking into the Alpha Pack's hideout before being captured and tortured by the Alphas. Although Peter did not get very clear information to where the two young Betas were being held captive, he heard a debate between Deucalion and the other Alphas seemingly planning to kill the two Betas on the next full moon night, which would be the next evening.

After being submerged in icy water and being interrogated by Alan Deaton, Isaac recovered his memories and revealed to Deaton, Derek, Scott, and Stiles that the Alphas had been holding Boyd and Erica in the vault of the abandoned First National Bank. However, what he did not remember saying was that he was locked in a closet with a dead body inside, which he identified as being Erica's. Derek refused to believe that she was dead and all of them decided to formulate a plan to rescue Boyd and the other girl locked with him. Isaac was presumably recovering from his hypothermia as he was not present when Derek, Scott, Stiles, and Peter were planning in how to break into the vault.

Once Derek and Scott punched their way into the vault, they encountered Boyd before meeting Cora Hale, whom a stunned Derek identified as his little sister that was believed to have perished in the Hale House Fire six years ago. Unfortunately for Derek and Scott, the Hecatolite mineral in the vault's construction had stopped Boyd and Cora from transforming for the last three full moons, slowly turning them into rabid beasts unable to control themselves. Once Marin Morrell completed a Mountain Ash circle around the vault, Boyd and Cora finally succumbed to their bloodlust upon feeling the moon's effects again for the first time in months and engaged in a pretty violet fight with Derek and Scott. Deucalion expected Derek, Scott or both to kill the young Betas as their initiation into his Alpha Pack.

Fortunately, Allison had sneaked into the bank without being detected by the Alphas and broke the Mountain Ash seal, saving Derek and Scott and setting Boyd and Cora loose, much to Derek's fury. Earlier, Allison hid in a storage closet under Morrell's orders to avoid being caught by the Alphas and found Erica's decomposing corpse inside. Derek later went to the closet to fetch Erica's body and carried it out of the bank in his arms, visibly saddened over her death.

In *De-Void*, Isaac, who had been infected by one of the Nogitsune's flies that increased his preexisting hatred towards the twins Ethan and Aiden, knocked the twins out with Allison's stun gun and dragged them to the locker room, where he planned to burn the twins alive with a Molotov cocktail. When he was putting his plan into motion, he muttered that he had to do this to avenge the deaths of Boyd and Erica and the twins had a role in both of them (albeit indirect it may have been). He was ultimately stopped when Allison and Kira Yukimura appeared and knocked the cocktail out of his hand. Alan Deaton eventually removed the flies from Isaac, Ethan, and Aiden, preventing the Nogitsune from controlling them anymore.
