[It doesn't at all surprise Martha to hear that the Doctor's been making friends. That's more or less what he does when he's left to his own devices (and when he isn't feeling sorry for himself for one reason or another).

In fact, both of them are an absolute nightmare to deal with.] They tend to be the most persistent about giving him trouble, so that would make sense. We had the Weeping Angels here once, although that was my fault. [She pulls her mouth to the side and draws in a hissing breath, sheepish.] I think that was before your time here, though.
