COULSON: Jeez, Mack. How hard did you hit him?
MACK: What do you mean- As hard as I could! Look, I don't half-hit people. It's a punch. That's why it's called a punch.
Simmons kisses Fitz on the cheek sweetly. Fitz scratches at his neck, and then, when the full weight of his emotions dawns on him, his face drops into an “oh, no, I really truly am feeling something fierce right now” face. Hit over the head with love like a fire extinguisher!
SIMMONS: And I'm allowed to want to save you!
FITZ: I'll save you every time or I'll die trying. I don't care!
SIMMONS: Me, too, because I love you!
FITZ: Yeah, well, I love you, too!
SIMMONS: Well, then, why are we yelling?!
