Brandon:

RIGHT NOW Brandon kind of reminds him of Hardball, so his initial reaction is "WOW WHAT A DOUCHE GET OUT OF MY FACE," but he's actually slightly less obnoxious than Roger (which is not hard.) PLUS he seems like he's probably a decent person outside being a douche and was in the Initiative under Osborn, so even though he doesn't know what happened to him there, he figures it's safe to assume it was just an awful time for all involved. He's not going to just up and start asking him about it because that would be rude, but it's something that makes him go "ah, you are probably not an awful waste of time."

also if/when they get to know eachother better Terry will probably end up being full on mother hen towards him. FAIR WARNING.

Reid:

Terry will be so charmed by Reid. I mean outside of his weird and disquieting profiler skills, Reid is IIRC a really nice, honest person who really wants to help people with the skills he has, which are all traits that Terry really likes and appreciates in people. (See: positive traits Terry refuses to see in himself.)

also they can be "way too young for their field of work" bros (Reid isn't that young anymore but shhhh)
