And then suddenly the floor below them began to rumble with such a restrained intensity that it felt as if the TARDIS herself was scolding her Time Lord.
The Doctor, previously caught up in an overload of emotions that could span across the color spectrum, responded with more surprise than he normally would have due to said emotional distraction. He stumbled forward and gripped the edge of the control panel, as his hand instinctively reached out to meet with his wife's.
"What the hell did you do?!" shouted River over the increasing noise level of the ship.
He scoffed extensively in order for her to hear it, "Why do you just automatically assume I'm at fault for," he indicated around them with a wave of his free arm "this?"
"Well, it is your ship!"
"Well, you seem to know how to drive so much better than I do!"
"And how does driving experience help a person deduce exactly what's going-", but her sentence was left hanging in the air, unfinished, as her gaze shifted from his face to over his shoulder.
With how her eyes widened, the Doctor almost didn't want to look behind him to figure out what had caught her attention. But he did and his eyes soon matched hers in size.
A giant wave of water, that he recognized to be from the swimming pool, was crashing down one of the countless hallways and directly towards them.
His mind didn't have to do the math to know that it was already too close for them to try and run.
