HAHA YES, something funky. Matthew only exists because of ~magic dream powers~, and as such he is not quite a whole person. His emotions are not complicated; he tends to be senselessly joyful and optimistic most of the time and has little to no idea how to be angry about anything. Quatre could find that as questionable as you like!

Also I noticed your other comment about him getting people to play with therapy pooches and Matthew would absolutely be happy to do that. PLAY WITH ALL THE DOGS.
