Yep as I mentioned in an earlier post that probably got ignored because of this "Caskett" nonsense "Killshot" is the sweeps episode which is why it takes place in two weeks right smack dab in the middle of sweeps. The promo does seem to touch on arc heavy aspects as Kate spirals "out of control" emotionally. It gives the impression that she has been hiding the emotional aspect of her recovery. I suspect that we will see Michael Dorn again. I'm guessing as mentioned above that it will touch on Joanna Beckett's murder which hasn't really been dealt with yet this season so it most likely be our first huge episode of the season after the premier.
