Well you can put him in the Blitz for awhile till Ace can start playing nicer with other. I doubt the sarcasm will ever go away but there is always a chance for him to start respecting the higher ups.
If we do that down the road, it could add a shitton of drama. It would also help a lot with character development. Ace either gets better and become a function member of the team or shuts down and become irrelevant.
We could also do this for anyone of the crew members.
