I was just editing a promotional picture http://www.malcolminthemiddle.co.uk/...php?photo=3552 of Malcolm from season 7 when I noticed a strange marking on his left arm. Then, I realized it was the same exact mark from http://www.malcolminthemiddle.co.uk/...php?photo=3654 I was just wondering if anyone managed to catch his tattoo appearing in any episodes during season 7 of MITM or did it remain hidden?
