Mark is shown very little but from what we see, he appears to be a hesitant person as he is very unsure if to accept Cesar's request. Possibly due to an encounter with The Intruder as a young child or the THINK Principal broadcast, he has paranoia and trust issues; He owns a gun in his drawer. Mark enjoyed writing about his life in journals since the age of about 5.Mark is a round-faced, fair-skinned young man with fluffy brown hair and eyes.
He is seen wearing a gray hoodie.
