Oh gosh! Then Ash has something he could give to her! See, he caught a Pokemon specifically for Madoka, so she could have a Pokemon who was keen to battle on her side. Sadly when she left Johto, it was returned to him; so he has Clara the Nidorina hanging back in his team.

That's if you want / if Mami would want her, once they've made introductions and realised that they both knew Madoka :x

( also Ash is just, a goofball who loves adventure but can get pretty serious cos he knows what it's like to be at the bottom rug of society and having to struggle to get by )
