I love their relationship. We saw a glimpse of his loyalty/gratitude towards Olivia last season, but its obvious that now that Stephen is gone (thank goodness gone but not killed off, so possibility of return could happen) I'm expecting even more scenes of them together.
I love this show, but the one thing I don't like is the relationship between Olivia and Fitz lol everyone seems to love it and it just doesn't click with me for whatever reason.
