I think that's ridiculous. The T is responsible for setting the appt. "time boundary," and I doubt you thought you'd be sitting there for a few hours as it were. (And I am still unclear if she ever told you how long a "normal" session with her will be in the future?)

Maybe warning you that she has an issue keeping her OWN schedule would be more appropriate, but that she does have a client right after you and needs to have your session wrapped up by 2...but then that would keep you on guard, wondering what time it was...and who can do the work they need to do in T and think about that as well?? So maybe that's a bad idea, too.

I think she should have kept her trap shut and be prapared to end in the session in a timely manner. If she has time management issues, that's her problem, and you shouldn't have to worry about them.

The Ts I have been too (besides attempting to reconnect with my childhood T, who thought timekeeping during a session was always the client's responsibility, but then we/she had LOTS of issues during this attempt...epic FAIL) have always declared themselves timekeepers and being responsible for ending the session. One T even had the clock behind me, so if I even wanted to think about it, I had to make an effort to look at my watch.

Anyway, I hope she turns out to be a good therapist and that the session does go well for you.
