This Sunday, “Once Upon a Time” is giving “The Little Mermaid” fans everywhere what they’ve been waiting for—the episode that focuses on the beloved Ariel (Joanna Garcia Swisher).

In this episode we get to learn Ariel’s connection to our main characters, especially Mary Margaret/Snow White (Ginnifer Goodwin).

A sneak peek posted on the “Once Upon a Time” Facebook page shows how Ariel met Prince Charming’s (Josh Dallas) wife. In the video Snow White is running from the Evil Queen’s forces (as usual) when she comes to a cliff. When the soldiers close in she has one choice—jump into the water below. Fortunately for her, there’s was a friendly mermaid there to keep her from staying under the sea (yea, I went there.) You can view the sneak peek here.

Another sneak peek, which you can see below, shows an interaction between The Little Mermaid and the famous villain Ursula. You’ll quickly notice that Ursula looks a lot like Regina. However, in a recent interview Access Hollywood recently asked Garcia Swisher if Parilla was playing the Evil Queen disguised as the Ursula or Ursula herself. She replied, “She’s Ursula!”

“Obviously, Lana, she’s an incredible actress, but it was so fun to watch her create this character and wanting so much to honor Ursula, but to also [wanting] to put her own spin on it,” Garcia Swisher explained.

She also hinted to AH that her character may be more than a one episode wonder. You can check out the full interview here.

“Once Upon a Time” airs Sundays at 8/7c on ABC.
