Since he was deadshots other target, we know Mr Freeze is in the game
Mr. Freeze - Villain. Unique. The first time you are the target of an attack, you negate it and disrupt the attacker for the next day phase. (This is not a disrupt attack.) You begin the game with 2 Ice Charges. At night choose one player to target, that night the player is then dealt an attack that both disrupts them for the next day phase and roleblocks them for the following night phase. (This counts as 1 attack, as opposed to 2.) You lose 1 Ice Charge. Once per game you may choose instead at night to hunker down. When hunkered down you cannot be the target of any actions or abilities, and cannot suffer any attacks. You replenish your ability to withstand death attacks and your Ice Charges back to 2.
