We have a bunch of great stuff about how his heightened senses etc can be a pain in the ass for Matt, so how about something where sounds/scents/sensations conspire to relax him instead? Maybe something at the office Foggy and Karen do which makes him all soft and sleepy in spite of himself, particularly after all his self-imposed sleep deprivation at night. Especially if they do it on purpose bc he needs the rest and sleepy!Matt is seriously adorable.
