Hey, that's a huge part of why he wanted to come along with you bro. He's here to do whatever he can to help, though he works best under distraction and defusion so... probably be a lot of trying to get Don's mind off the main subject and on to other things, training, science-y stuff, smart things... that kind of stuff. But he's just as ready to give him hugs and hold onto him when he needs it too.
