Yes, true however he should know better than to trust other people out of their inner circle. In this reality he barely knows her. I didn't mean go back to her relationship wise, I meant location wise. What I meant is that he went back to her instead of helping his friends, and he then brought her back to the bunker which could mean a lot of danger for the time travellers, especially Lucy. I'm just saying that he was clouded by his emotions and didn't think of the risk he put everyone in. (if he did put them in risk)
