Very cute scene between Mac and Jo at the end of friday's episode. They truly seem to be developing a very trusting relationship and I loved how Jo was able to open up to Mac about what was going on with Ellie. That moment in the office with Jo confiding in Mac and Mac being there for her was really nice to watch. But the end was what really made me smile. The way they were just talking and making fun of each other was priceless. I loved that Mac teased her about her messy desk and that he invited her to grab a burger. His "Jo, stop" made me laugh. It was a nice scene to watch and Mac being so loose and smiley is a treat. Their chemistry is really nice though I am of the opinion that Sela has chemistry with everything and everyone who stands before her . Good Mac/Jo episode .
