Roan led Murphy and Clarke to the secret exit out of Polis in the midst of Ontari's coup but then essentially washed his hands of any debt owed to her. What side is Roan on now? And why is Clarke looking at him with the incredulous look on her face?
While it's great to see Roan again after his long absence, we have so many questions. Where has Roan been? Is he chipped? Who captured him and how did they do it? We've seen people attempt to overpower Roan before and (except for Lexa) it's pretty much impossible.
