Marcus Cole is a character in 13 Reasons Why. He is the subject of tape 6, where he is responsible for humiliating Hannah Baker in public on their One Dollar Valentine's date. He is portrayed by Steven Silver.
In the flashback, Marcus supposedly got Hannah Baker for his #1 for the Dollar Valentine event. He proceeds to ask her out on a date at Rosie's, and she said she'd think about it. She made up her mind and said yes, but didn't realize that Marcus is using her because she is "easy". Marcus then shows up an hour late and drinks out of her milkshake. He moves to sit in the same side as Hannah, but only to make a move on her. He then got pushed onto the floor, then leaves with the guys he came with in the end.
