Like...immediately after my, uh - memory...thing? Burst? [ It didn't look like a bubble inside so he feels weird saying that? But Katsuki's looked like a bubble from the outside, so... ]

I was just underwater and luckily could breathe since I was pretty far down. [ He's not sure if being crushed in the water here is a thing or not. Is his body protecting him from the deepest depths, or is that some weird...Quirk? ]
