The movement Eva makes draws the Doctor's attention to the gun. He frowns at it all rather pointedly. Not much of a fan of guns in his ship, actually, but it's too late and at this point, he thinks he can make an exception.

"Well," the Doctor turns toward her, his hands clasped in front of him like he's a professor lost on his way to his own class. "They're both going north and not north. We could split up and each take a path or we could stay together."

He turns slightly to eye that gun, distracted by it, and then back at the paths. The truth is right now he's feeling less than brilliant right this very moment and anything less than brilliant is no good, in his opinion. You didn't get anything for Close But Just Shy of Brilliantly Amazing, after all! Considering how the encounter with the library turned out, the Doctor doesn't fancy splitting up. He likes the idea of sticking together and besides, in a forest as dreadfully dull as this, he could use a friend to talk to -- it's either that or he'll end up talking to himself and that generally tends to get old, fast. Gun and bad language aside, he finds Eva good company, so he's hoping she'll want to stick together too.
