Blaine was a clapper. He didn't care for much, except the people that were in their group at the Graveyard. When he was caught and sent to Happy Jack Harvest Camp to get unwound, he became a clapper with Mai and Lev. Blaine was shot in his thigh by a Juvie, causing him to explode.
Blaine hopes to become like his brother, whom he sees as hardcore. For this reason, Blaine chose not to use the detonators to explode. Blaine also gives off a sense of aggressiveness.
