Matt standing up to leave the office and leaning in to kiss Foggy goodbye. Foggy accepts without realizing anything. Foggy moving in Matt's house because he can't sleep thinking about Matt hurt and nobody to help him. Matt pushing Foggy to sleep on his bed with him because, "I don't mind sharing and it's better this way for the both of us." Foggy dressing Matt's wounds, smacking kisses on his wounded cheek so it'll heal faster, Matt invading Foggy's shower to shave, Foggy helping him shave....

Just things like that.
