That sneak peek kind of sucked monkey balls. Shockingly underwhelming. I found the writing & staging incredibly clunky, and Lana didn't help stomping around and huffing like a petulant teenager whose parents told her she couldn't have the car tonight, and insulting people who were in pain. That should have been an incredibly emotional scene, and it came off as rote and cold. And, of course, the writers & Lana made it all about Regina, except for a brief bit of Hook. (Colin was legit the only one I felt emotion from.)
And Hook & Regina will disagree on how to help Emma. Anyone doubt that Regina will be proven right in the end? Since it's TS, TW.
