Two weeks ago Arrow ended with Sara Lance being brought back to life. Last week ended with her breaking free of her chains and escaping Laurel's basement. This week ended with her supposedly back to normal. They don't hang around in Arrow. Understandably, after all of that, Sara was in need of a bit of a rest. However, you imagine she's going to need a lot of time to process a few things. There's the fact that she was dead a whole year, for a start, and then the small matter of being brought back to life and going on a killing spree, which included trying to murder someone you've known most of your life. It's not going to be an easy process for Sara, so how will she react to it all? Is this what prompts her to leave Star City and join the Legends of Tomorrow (which, let's face it, is the only reason she's been brought back here)? At the rate the show's going, it'll probably be resolved by the end of next week.
