1. Yes, I saw a T through my doctor's office when main T was on vacation.
2. It was a good idea I think, if you feel you need it you probably do. She had a different working style than my own T but I think she genuinely wanted to help. It wasn't 100% satisfying but it was a long vaca and it helped some.
3. No, my T never spoke to her but I did give her a brief history
4. She did a fair amount of talking too, and she was a fan of zeroxed "pamphlets" on different studies and topics--that part was 1/3 useful and 2/3 distracting
5. It was ok. Felt like I was "cheating on" T but he was ok with the idea
6. No, it helped me be less frantic on his return

Hope this helps!!!
