Put on a jacket because it's about to get cold. Once Upon a Time is new tonight, and according to some spoilers, viewers will get to see how the Snow Queen and Regina first met. While fans of the series got a little bit of background into the history of the Snow Queen, who they also learned is named Ingrid, tonight's episode will dig deeper into her past, as the Season 4 episode is appropriately titled "The Snow Queen."

According to TVLine, the Evil Queen and the Frozen royal had a run-in with each other while Regina was mayor of Storybrooke, and viewers will get to see that during tonight's episode.

When Emma and Elsa finally get their hands on Ingrid, Emma brings her down to the sheriff's station for some questioning, which is how fans will most likely get the background info on the icy villainess.

According to the International Business Times, when the Snow Queen tries to use some information she has on Emma to persuade her that they are more alike than she thinks, Swan's magical powers go haywire and cause havoc in her town.

Also set to take center stage in this episode will be Regina and Robin Hood's complicated relationship, as they try to find a way to save Robin's wife Marian from an icy death. We are sure that some sparks will fly between these two, which will give all the Regina and Robin fans out there some hope.

By the way, we think it's about time these two got a celebrity couple name. What do you think?

The episode will air tonight on ABC at 8 pm.
