Revenge returns Sunday night with the first of two episodes we've been waiting months for. The entire second season has been building up to Jack and Amanda's wedding, and the potentially tragic aftermath.

ABC has released an extended trailer for their "Union" and possible "Sacrifice." Take a look:

The synopsis for Sunday's episode hints that "emotions run deep when Jack and Amanda’s wedding reminds Emily of what could've been." The clips above (and photo gallery) drive that point home.

That's February 10. A week later, on February 17, "Jack and Amanda sail off on their honeymoon but the seas prove to be deadly, and this time Emily can't control the outcome."

Again, that ominous tease looks like an understatement based on the new trailer. What/who does Jack find down below? Who is the shooter on board the boat? Is Emily involved in the fight?

Revenge Season 2 began by showing us a body in ocean. We're almost to the point of the big reveal, but what happens in the aftermath of this game-changer may be the real story.
