I don't think that they did anything really to hurt her, since she was so fragile and Finnick would never tell her anything that might get her in trouble. The Capitol just needed something to try to get Finnick to break, as Snow did to Katniss with Peeta, probably so he would be weak (seeing how unstable he seemed in 13) and not so much an inspiring rebel. It's been a while since I've read Mockingjay though, but in still totally TEAM ODAIR AND CRESTA (aka TEAM ODESTA)!!!!!! <3
