William is the other Lieutenant at the precinct and the one person considered as the most reliable member of the MIU squad.
He appears to have a soft spot for the MC and a never ending quarrel with Eliot - and also an obvious liking for coffee.
He's known for also constantly breaking stationery, thanks to his inhuman strenght and lack of patience.
Liam is the tallest and strongest member of the unit, and seems to be act like the enforcer. His skin is tanned and he has pale gray eyes. He's always wearing a white dress shirt, suspenders and a black tie.
Liam can create red strings of power and use them to bound and restrain the enemy.
