I haven't got a plan for Juniper right now, I know you suggested Kyurem but I have other ideas for her.
Maybe Juniper could go the same way as Erika, she'll bang you if you've already banged Hilda Rosa & Bianca, they all talk to her about their adventures and she can't resist after hearing so much about you.
