==Blurb==
We come across a disguised Team Rocket, pretending to run a Pokémon Day Care and promising they can evolve anyone's Pokémon in two hours! A young boy named Roland agrees to let them do just that. He leaves his Magby with them. Later, when Ian runs into our heroes and tells them what he's done, they become suspicious of such a claim. But when they all go back to the Day Care, it's gone!
Roland immediately decides to tell his mentor, Bertha, about it. Brock is shocked to recognize Bertha as a member of the Elite Four, but Bertha asks Brock not to tell anyone. Bertha begins to guide Roland and our heroes in paying close attention to the details of the situation, and they soon come across the disguised Team Rocket in yet another location, trying to steal more Pokémon.
Some fierce battling ensues, with Bertha teaching and demonstrating the "power of observation." But when Team Rocket attempts to outfit their Pokémon with what they dub "Powering-Up Parts," that is the last straw! Team Rocket is sent blasting off again, while Magby is safely returned to Roland.
Bertha and Roland thank our heroes for their help. Bertha asks if there is anything she can do in return. After discovering she's a member of the Elite Four, Ash requests a battle with her. Although Ash and Torterra lose the Battle to Bertha and Hippowdon, Ash gains valuable experience and practice with the power of observation, and Dawn discovers how valuable careful observation is for her and her Pokémon Contests, as well!
==Plot==
A disguised is running a phony Pokémon Day Care, promising s to evolve any left in their care within a two-hour period. A young Trainer with a passes by and Team Rocket easily talks him into it. They take him inside their makeshift shop and tell him about their plan. While the Trainer is excited, Team Rocket fantasizes about giving Magby to . The Trainer leaves Magby and his before leaving.
Meanwhile, and arrive in the same town, en route to Lake Valor. The same boy crosses their path and is excited to notice a cute Pokémon. He takes interest in Ash's Pikachu, which upsets 's . After quick introductions, Ash lets Roland play with his Pikachu in a local park. Dawn wants Piplup to play too, but he is still upset. When asked about what Pokémon he has, Roland mentions his Magby, which Dawn looks up. When asked to see it, Roland tells about his earlier action of letting the Day Care evolve it in two hours. This instantly gets the group's attention, knowing something is amiss with such a promise. When Roland takes them to the shop where he left Magby, they find it completely locked up. The building is also bare, with the signs gone. Roland realizes his mistake and needs to inform Bertha. That name gets 's attention as someone calls out to Roland. She introduces herself as Bertha. Brock feels that he knows who she is, but before he can say it, she drags him away and confirms she is part of the Sinnoh Elite Four, but she doesn't like being called by that title, so she tells Brock to not say anything. Bertha wants to train Roland, but when he says his Magby was stolen, she is clearly upset. Roland is related to Bertha, a child to one of her cousins, and that she was asked to train Roland. She lectures him on responsibility and to correct his mistake. Ash and his friends decide to help. As they walk, Ash and Dawn share their goals with Bertha as she asks about their plan to search, which stumps them as they have been searching aimlessly.
Ash spots a building with an observatory and suggests going there, which pleases Bertha. At the tower, Roland uses a binocular stand to look around, spotting the same shop in a different location. When Ash and his friends confront the owners, they try to deny it, but their disguise fails when the shop crumbles by Jessie's hand. They use pink smoke to cover their escape, distracting the others, but Bertha steps out of the way. They proceed to chase Team Rocket, but Ash suggests to split up and box them in, pleasing Bertha at his planning. They almost box Team Rocket in, but they run down another street into a field. When Ash and his friends follow, they run into a series of Windmill towers. It looks like Team Rocket is safely concealed, but Bertha tells them to observe any disparities. They notice one of the towers not spinning at all.
After being spotted, Team Rocket knocks over the fake windmill tower they were hiding in, inflating their balloon and taking off. Ash sends after them with , but Meowth simply reacts by activating a Staraptor-shaped "Aerial Ace Defense" mecha under the balloon to knock out Staraptor before it could attack. Bertha responds by saying that there is now only one way to do and soon everyone is sent on a wild hayride in her SUV. Once Ash spots the balloon, Bertha sends out her and prepares for a attack. Meowth once again isn't hazed and responds by activating a Gliscor-shaped "Guillotine Defense" mecha. However, Gliscor easily destroys the device and bursts the balloon, too.
Once the balloon crashes, Ash and his friends confront them at the crash site but Jessie and James are not going to get away without a battle; they bring out and while Ash and Dawn respond with and . The two Pokémon easily dodge their attacks, while a from Buizel strikes the crooks, allowing the heroes to recover Roland's Magby. Bertha suggests to Roland to now join the battle, to which he summons Magby and while taking a from Carnivine, it retaliates with ; significantly damaging Carnivine. Team Rocket; fustrated with losing once again, resort to a sneaky trick as Meowth launches some powering-up parts to increase Seviper and Carnivine's power, much to the shock of Ash and his friends. With their enhanced power, Carnivine and Sevivper easily knock down Buizel and Pachirisu. Team Rocket gloats at the heroes, but Bertha angrily scolds them for tampering their Pokémon to gain an unfair advantage. Jessie and James, offended by her remarks prepare to attack her; to which Bertha simply sends out her and uses , destroying the powering-up parts and knocking them out, surprising Team Rocket. While Ash and his friends are all amazed at Golem's natural strength, Bertha has Roland attack with Magby's and sends Team Rocket blasting off again.
Everyone is impressed by Bertha, and Brock slips that she is an Elite Four member. She confirms it to be true, despite her dislike of being called by that title. She thanks them and Ash requests a , which she accepts. On the field, she summons . Ash checks the Pokédex. So he summons . Ash orders a , but Hippowdon dodges by . Hippowdon comes up from under Torterra and quickly strikes with . Torterra takes it and gets back up. Torterra uses to raise rocks all around and charges, but meets with an Iron Head. The dust consumes the area and all the Pokémon are slowly revealed, Hippowdon still standing. Through the dust, Bertha encourages Ash to be more observant in battle as well as in life, which is a useful skill all around.
Hippowdon goes back underground as Ash observes. He remembers that rocks would shake before Hippowdon emerges. Ash spots the rocks moving behind Torterra, ordering it to dodge and fire Leaf Storm. The move hits, which impresses Bertha, but Hippowdon recovers and goes back underground. This time, Hippowdon circles around Torterra from underground, making it impossible to predict where he will come up from and dodge. Hippowdon strikes with another Iron Head, launching Torterra into the air before biting with and throwing Torterra down, giving Bertha the win. Ash tends to Torterra and accepts the loss, while Bertha encourages Ash to develop his observation skills while praising his ability to take pressure.
