Dean and Sam scrounge up like a few extra hundred dollars to go to a dirty, cheap tattoo parlor so they could get the antipossession tattoos. Dean jokingly asks Sam to hold his hand if it hurts, and Sam just rolls his eyes.
Anyway, it was buy-one-get-one-free. So now Dean has a small "s.w" on his hip, and Sam has a matching "d.w". (It's not like a couples tattoo, because they can't break up/ever be apart. or else they will combust into flames).
