Yeah, I'm with you on not wanting any sort of Renee as surprise spy ending here. I can certainly speculate numerous scenarios with her as spy for the Russians/others, but honestly I just want her to be a regular citizen. I was initially amused by the Renee as spy teasing on the show but now I'm just annoyed by it, to be honest. I'm hoping that the entire Renee tease was just the showrunners way of emphasizing how paranoid people in the espionage biz get after a while.
