For me what stands out as a mistake here is your T saying her bf looks like George Clooney. What was the purpose of that other than provoking you? Trying to redirect your attention might have had good intention in the background, maybe she just did not think about it carefully enough.

What I would probably do is tell her that it was confusing that on one occasion she asked you to think about your question in depth and then she did not want to discuss it. I would ask her straight why she turned down what she proposed herself earlier, and would not let her sneak out of answering. And I would tell her that throwing up the George Clooney thing was provocative and unnecessary.

Then maybe move on
