LOL! I don't think she's "his girl", she's just one of those momentary pastoral temptations that Mark often finds himself faced with as he goes about the wilderness doing nice things for people and animals in need. Mark has tremendous self-control, so not to worry. He has never fallen prey to the baser instincts or given in to the allurements of unmarried women!

I note that Mark is noticeably unshaven in those pictures! This must mean that he has just emerged from some terrible test of survival in the wilderness which required him to subsist for days or weeks with nothing but a compass, a pocketknife, and his wits.

That ain't easy, lemme tell ya.
