So who do you all think may have been the actual traitor in the beginning? I know King is a prime target but he only had a reason to attack the rest (and by rest I mean Ban whether or not he is with the group or not) after he went back to his hometown. Plus he had to hide because the sins were called criminals.
Honestly I can't really think about who could be the traitor. I know not all have been introduced but considering how the sins have been showcased so far it is hard to imagine that someone in this group would betray them all. I mean Ban seems like the most obvious but he shows a lot of respect for the captain so it is probably not him.
Whoever it is it will probably hit hard. Cause all these main characters are awesome.
