Question: What spills onto the floor in the hotel fight when the toilet is broken? It looks like some form of insulation.
Answer: From what I could tell, at the beginning you see a smoky glass partition (or glass-like) by the toilets. I couldn't really tell what for, maybe a changing area. Before the toilet gets broken, this partition gets shot and shatters. That's what's on the floor. But I can't see how it could get around the toilet like it does without some mistake.
Answer: This is true of all versions of the character - his name's officially John Patrick Ryan, but he always goes by Jack.
