Julianna
Chris really seemed to connect with Julianna. She wasn't some coomar he kept on the side. Yes they spiked up together and loved chasing that dragon but he really opened up to her.
The time they were sitting in the diner and he was telling her about how it works when you join the mob, you burn a picture of a Saint and prick your finger. And how that conversation left off who knows what else he told her.
Then a few times you hear him say things about Tony and how she could never have him find out that they're together. He revealed alot of info to her. If their was any woman who could of steered him away from the mob and Tony I think it would have been her.
