Just for the record, I have absolutely no basis for this speculation, but after watching ep 11, it occurred to me that we have two possible solutions for Jonas Armstrong leaving the show. Seeing the introduction of Archer, and Guy's apparent change of heart, it seems possible that we have 2 candidates for leading the gang in season 4 (assuming the show gets renewed). I do find it difficult to believe the gang would ever accept Guy as a leader, but Archer is a distinct possibility. I know we've seen in the trailer for ep 12 that he tries to work for Isabella, but we also saw his good side when he was so insistent on saving all of the people in the dungeons in York, and his attachment to the old man. What does everyone else think?
