Rooster of Doom

Corrected entry: Hyde swims underwater and pulls a lever in the engine room that opens the drain. It looks tough for him to move the lever, he puts all his strength into it and it takes him several seconds. It's a pretty meaty lever. But the sub's designed to be operated by normal human beings - how would a regular person ever be able to operate that lever?

Correction: The most obvious assumption is that the linkage or drain parts have been damaged by the explosions, rendering them nearly immovable.
