Doneo

**Doneo** (**Don**/ald and L/**eo**) is the father-son relationship between Donald Davenport and Leo Dooley in *Lab Rats*. Donald gained Leo as a step-son after marrying his mother, Tasha. Since Leo's biological father is never mentioned, Leo appears to be close to Donald as his father-figure.

Leo mainly calls him "Big D" because of his position as head of the Davenport Household. However, Leo doesn't have the best relationship with him, even admitting he's not all that good. Despite teasing each other, the two care about each other.

They are sometimes called **Deo** (**D**/onald and L/**eo**) or **Lonald** (**L**/eo and Don/**ald**), but rarely.

## History

Throughout the series, Donald tries too hard to bond with Leo, and once blew it with him when Donald revealed to Tasha Leo's secret crush when Leo wanted the secret kept between them.

In Bionic Birthday Fail, Donald hopes to make Leo's first birthday with him special and he does this by buying his stepson a hexacopter. However, Donald accidentally destroys it and tries covering it up when Tasha tells Donald to give Leo his gift for him. The incident causes Donald to realize how he was a terrible father and hoped to make it up to Leo. At first, Donald thought Leo could not handle the simulator but changed his mind when Leo took out a rebel. Later, Donald created a new hexacopter for Leo, but he ended up destroying it on accident.

In "Can I Borrow the Helicopter?" Leo opens up to Donald about his secret crush on Janelle and asks for his advice on how he can approach her. Though Donald promises to keep it between them, he becomes to proud of establishing a father/son bond that he reveals to Leo's mother on his crush on Janelle. Donald later apologizes and makes it up to his stepson by letting him borrow his helicopter to wow Janelle

At the time of season 2 Leo and Donald appeared to get along better, as Donald begin trusting him with missions and being a part of the team. He is fairly protective of Leo as much as the Lab Rats, as he refused to let Leo go on a moving, speeding train. Donald seems to believe Leo about his adventures in a parallel world and that Leo is telling the truth about Marcus being evil. When Leo turned out to be right, Donald regretted about not believing him about it. Later, Donald shouted for Douglas to leave his son alone when Douglas sent Marcus after Leo. However, his son came at the last moment when Leo busted into Douglas' lair in Donald's exoskeleton

Since Leo matured, Donald finally trusts his stepson, like allowing him to invent things in the lab without Donald in the room and allowing him to find sponsers for his J-Wing stunt. Donald was also concerned for Leo when he learned that his son had been gravely injured, especially when the family feared Krane had kidnapped Leo again; Donald was relieved to see his son and Douglas when they were cornered by Krane and Donald immediately asked Leo if he was alright. However, Donald was angry to learn that his brother gave his son bionics, fearing Tasha's wrath. The Bionic Academy is founded, Donald passes Leo over as a mentor and tells him he has to be a student instead. At the end of Season 3, Donald promotes Leo to a higher level, from beginner to intermediate. In "Unauthorized Mission", Donald is nearly killed trying out Chase and Sebastian's latest virtual reality stimulation, causing Leo to rush to Donald's side and look at him in concern. Unknown to them, Sebastian rigged the stimulation, hoping to get revenge on Leo, the rest of the Lab Rats by taking away their father.

Donald does consider Leo his son, according to the episode "Bionic Houseparty." In "On the Edge," Donald proudly announces Leo is the next mentor after he proves to be courageous in battle by rescuing their family from the Hurst Memorial Bridge. Leo was also happy for Donald and Tasha when they announced that they were going to have a baby girl together.
