The last thing Toby said to me (during our 10 second TS1 call) was that I was on the "shortlist for admission." Which is why I'm still holding out hope.
Yea, I wouldn't worry about it. The only thing that would make me worry is if more TS1's go out before you get a TS2. I don't think not getting a call is reprehensible or anything, unless he specifically promised he would give you word in a few days. You seem pretty chill about it, which is the right attitude. Just keep your fingers crossed. Someone will get admitted shortly (or at least a couple over the course of the summer) and you're a few steps ahead already.
