I certainly think that would qualify as a "worst day ever" for sure!!! How terrible. The ending really threw me for a loop, I wasn't expecting the cross-over between the partners and Catherine!!!! Sounds like next week's episode it going to be different too - four different storylines. That will certainly keep me guessing the whole time!
Oh, and I totally second Lady Heather's return (if possible, I can't remember whether she ended up in jail or not either!). I liked them together as well!
