Thank you! I already have some idea of what Pokemon I want her to be able to bring in. They're not legendaries (nor are they pseudo-legendaries). One of them is also a flying-type (who will probably also serve as her mount due to mobility issues), so that one can use the loft.

One more question: would other Pokemon be regainable at a later time, or is she going to have to live with her two the entire game?
