On Season 2, Episode 16: "The Miller's Daughter," Regina (Lana Parrilla) was tricked into killing her mother, and in this sneak peek of Once Upon a Time Season 2, Episode 17: "Welcome to Storybrooke," we get a sense of just how upset Regina is.

The sneak peek begins with Regina crying over her mother's grave, a sight so sad that it will probably break your heart a little even if you're not a Regina fan.

Her mourning is interrupted by Rumplestiltskin (Robert Carlyle), who shows up to "pay [his] respects" to his lover turned enemy. Regina, however, is not amused at his presence.

"You killed her to save your own life," she accuses, before adding that even if Rumple can "hide behind [his] dagger," Mary Margaret [Ginnifer Goodwin] has no such excuse.

"She is going to die for what she did," Regina promises.

Given that it's freaking Snow White we're talking about, we're 100 percent sure she won't actually get killed off. But it'll be interesting to see how she manages to escape Regina's wrath.
