i helped her my first time and sold her out my next time. whats great from that quest is i dont think there is a a right choice. She could be lying or he could be lying. even the Skyrim wiki doesnt say that theres a right answer. It actually says she was most likely lying.
Ever since I saved her there have been some Alik'r standing inside the gates of Whiterun. Bitches wont leave either. Everytime I come into town they give me the evil eye... It's all i can not to bitch slap 'em both.
