Yeah, she befriended a Hoothoot and then we tangled with a Larvitar for a little while and then we ran away and then the Hoothoot was still with them so Alyssa asked it if it wanted to come along with her and it did.

Does Leah know that Alyssa is specifically afraid of Dark-type Pokemon? I know Alyssa said stuff about her fears but I don't remember exactly how coherent she was.
