Alice really doesn't give him room to argue, but Thanatos also decides that if the ground suddenly opens underneath their feet, he's flying them the rest of the way. He can float. Alice cannot. (Or at least he has never seen her float.)

Too bad Alice's White Rabbit isn't here to give them direction to start with if they are going by foot. A loud crash then fills the air somewhere behind them. Thanatos looks at Alice. Start in the direction away from that?
