Definitely Jun…she’s a wise woman…Zafina probably second but it would be confusing given that she talks mostly in riddles at times…Jin obviously has the worst leadership reputation being a warmonger and all(even if it was for good reason)
I feel like Jin after all Jun and Zafina maybe might be good for that but hard to jugde because screen time is last thing Zafina will get and as for Jun she's actually only in Jin's mind so
