Something tells me these two aren’t gonna get along

After all, they did have a rude first encounter.

May had quite a rude encounter upon meeting her rival Drew for the first time

She wasn't very fond of his stuck-up attitude.

Jessie finally realizes she has a Cascoon, which will evolve into Dustox

On the other hand, May's Silcoon will evolve into Beautifly.

Jessie and May both had Wurmple, but only May’s Pokémon will ultimately evolve into Beautifly

That's because Jessie's Wurmple evolved into Cascoon, which eventually evolves into Dustox.

May tries to explain to Jessie that their Wurmple happened to evolve into different Pokémon

May's Wurmple evolved into Silcoon, whereas Jessie's evolved into Cascoon - despite her believing otherwise.

Jessie and May both had their own Wurmple, but each one evolved into completely different Pokémon

Jessie was so convinced that hers evolved into Silcoon, but boy was she wrong.

May and Max know the true value of siblingship

If they work together and have each other's backs, they can accomplish anything.

Looks like Ash is being teased by Brock, May, Max and even Pikachu

At least they seem to feel pretty bad about it.
