While in his cell prepping for his visitors, John Kelly plugs the sink and leaves the water running. When his visitors are about to arrive, John stands with the sink behind him which is about 2 inches from being full. In the next shot, from John's side, the sink is violently overflowing.

When the door between the cargo hold and cabin is open, the entire cabin is now unpressurized and everyone should still be on oxygen.
