Alex wasn't too sure what shooting off a flare gun inside of a sub that all ready had a hole in its side would either, and he had really been hoping to bluff his way out of having to try.
Before his finger could squeeze the trigger though, the water had rushed him with surprising force. The flare fizzled as it shot off into the water, and Alex dropped the gun, trying desperately to figure out which way was up so he could take a breath. The more he panicked, the quicker his oxygen dwindled, and fuck hadn't he had an air canister in his hands like five minutes ago where the hell was it when he needed it.
He held off as long as he could, but his body demanded he take a breath, and as he inhaled, the water made him cough, letting more water flood into his lungs. Soon, his eyes were glossy, and any struggling stopped.
