I would love to write Don pov fic, if I could just work out what was going on in his head.

I don't know if it's so much that he doesn't trust the team, as that the team aren't really greatly relevant to what he feels he has to do. He does trust David to wait off and not shoot Buck on sight, although if he was originally planning to duck out without backup we're back to not trusting, not to mention deathwish.
