The TARDIS hovers meters above the churning waters of the bay. Rose stands at the doorway, watching two large silhouetted shapes disappear beneath the surface.
"You didn't tell me you spoke Whale," she says, slightly impressed.
"I don't." The Doctor shrugs nonchalantly. "The whales spoke a highly primitive dialect which shares remarkable linguistic similarities to the major language of the planet Rorqualis: Rorqualese. Although... to those two I probably sounded like a caveman explaining how to cook a French omelet. You know, 'ugh egg' this and 'me break shell' that."
"Well, they got the point, yeah? They're headed out to sea now. And no one will know what we did here, what you did."
"Oh, everyone knows whales are clever. The experts will think and theorize that the whales sorted everything out on their own, which is mostly true."
Rose smiles widely, amused. "But at least you were here to give them directions when they got lost along the way."
