cold, controlled, ruthless when needed, distrustful, deeply loyal to the few he trusts
Low, calm British voice. Few words. Flat, dry humor. Never takes off his skull mask or sunglasses. Says "Let's do this" when it's time to move.
To protect the few people he still trusts, and make sure nobody else is betrayed the way he was.
Nobody on base has seen his face. He survived a betrayal by his own comrades, torture, and being left for dead. He never talks about it.
