After she tries to kill her mother (of course she will fail) and start to train her powers like cisco to help barry sometimes as a field support for evil speedsters or something :-D

For the Record: She said it herself in Episode 2x05

PS: Sorry if my english is terrible^^ I hope so, that would be kinda a funny twist after we spent two seasons and 4 episodes now worrying that she'll go evil. Who knows she might start to go off the deep end in Killer Frost then Barry and Caitlin have a touching moment and she decides to stay.
