Easy. Lancefer. He’s the oldest an most mature of the three though Dest is in a close second. Lance takes his role as a knight very seriously. He may put up a front of an easy smile an joking behavior but he will be totally serious in a heartbeat if the situation calls for it. He bears a lot of heavy responsibility. So while he might wear a mask of someone more light hearted he is a very mature person overall.
Dest still has too many personal issues to beat him in being the most mature. But she can be very mature when the situation demands it.
