I'd still interview new T for two reasons. First, you say you don't see yourself long-term with the older T as you don't think she could perhaps 'get you', smell etc. And unfortunately, you don't know how long your T will be unavailable..

The second reason is that by interviewing new T, you can ascertain what the situation is in actuality I.e. whether she works with your T or would report to her in some capacity or whether she will be a completely separate agent, so to speak. In which case, the fears -or valid reasons- you raise might no longer be an issue. Now she is an unknown quantity but she might be someone you really click with or with whom you could talk about specific issues and so on. So by seeing her at least you'd have all cards on the table for a, more or less, 'informed' decision.

Again, this is so as to leave all your options open as you seemingly don't now what is going on/going to happen with regular T...

It's good that you found a new T though.
