[There's an almost stuttered sort of pause as he stares at Fitz for moment, the momentary shock coloring his features. The fact that he's letting him hold any kind of deciding factor in this is...more important to him than Fitz probably realizes.]

Look, I know that you guys have...your issues, and I get it, I respect it, but...the Caitlin you got off on the wrong foot with is...nothing like the one I know. [There's a slight pause, and he decides against going into a spiel about her, making it seem like he's trying to sell her to him; instead, he leaves it simple:] She's one of my best friends, Fitz. I'd trust Caitlin with my life. And I'd trust her with this, too.
