I don't suppose -I- could update Sei before round 2, even though he didn't level?

And can anybody help me learn how to play a level 6? I'm so used to downplaying Sei's abilities that when I started treated him at his current level, I was penalized for three conclusions. I'm not complaining, it's a fair judgement, but a lot of it has to do with the fact that I'm so used to not playing my character as if he's level 1-2 that I don't know how strong a level 6 is supposed to be.
