The Doctor was more than willing to have Barbara link her arm in his, giving her hand a pat even as he fixed the Kessek with a look and a frown and was that a slight furrow of the alien’s eye ridges he saw? The alien shifted his big feet from side to side, starting to get that idea that maybe, just maybe, he had something to say.

“If you know something, you are obligated to tell me,” he rumbled. “If the Daligig are compromised, you are compromised.”

“Stunning logic,” the Doctor said. “Very difficult to argue against!”

So maybe they did have the Kessek's attention after all.
