If it was me I would not go for the interview but it would not be for any logical reason, it would simply be because I would die if I thought there was a chance my T would see me attempting to function in the real world all the while knowing what's going on in my excuse for a brain. I could never concentrate on my job if I thought she might spring up at any time and send me into a downward spiral.
If you don't have that issue you should most definitely go for the interview! And you can bring it up with him or not bring it up with him. I think either is appropriate. Good luck
