I’ve had a couple of people ask me about to and about the fact that when I drew, e.g., try-sentences on the handout, I didn’t draw to moving to T.

And, in fact, to does not move to T. We learned this back on homework #5, with respect to the sentence I wanted Joss not to have been making movies. It’s something special about nonfinite T (or, perhaps, the movement of the highest auxiliary to T is something special about finite T).
