''We may not be really related...''

''...but I can teach you a thing or five.'

An idea my friend give me. See in our fanfics, TC is under the training of Grim who (If you read the comics done by Bleedman) is also Jack Skellington's half brother...and Jack is Wing's (My oc) adopted dad. So in a way, that makes both Wing and TC cousin.^^ Course like all family members, the two don't alway see eye to eye but they still care for each other.^^

Hopefully it turned out all right.^^ I know the t-shirt and jeans are both meant to be black but I made the jeans a bit lighter so you could tell it wasn't a suit TC was wearing.
