Quite a while ago actually, but it was more covered on the Tumblr Ask Blog than anything else. When Ace/Jules fled Ohana, he left three of his Pkmn behind to Taz - two of them (Geist & Biss/Arbok) were more than happy with the development, with Geist evolving as a result of this sudden change of trainers - the third (Hitze/Infernape), took a while to adjust and eventually went back to him when he returned to Ohana.
