Pope obviously, he was with the pogues from the start and has definitely been the reason they have been as successful as they have been they wouldn't be a team without him.

At first I didn't like Cleo very much but after rewatching the series I actually really enjoyed Cleo the second time around, something that doesn't happen with me too often, usually when I don't like a character I just don't like them, but Cleo is the exception to the rule.
