"I'm not sure... how. I haven't done this before." Cuddling. It's clearly cuddling, and it's not something that Ed or Riddler has context for. Maybe, when he was very small, his mother had held him once, but it was before even his eidetic memory can recall and he can get back to around three years old and his parents screaming at each other in the kitchen while he watches them and doesn't understand.

He takes a slow breath. "I don't mind breezes. I don't like being cold with no wind, but with wind is okay." It reminds him he's not in the ice.
