The long wait is finally over for Frozen aficionados. Queen of Ice, Elsa made her icy debut at the season four premiere of the high-anticipated series Once Upon A Time. The chilly entrance of Frozen's favorite characters brought a blast on the show that premiered on September 28.

Pushing evil queen Regina aside, the drama and trouble in Storybrooke is more profound than ever. While Hook and Emma were figuring out their relationship, Frozen Fever took over. The fourth season was announced on May 8, 2014, which revealed a new storyline at the conclusion of the third season finale.

Once Upon A Time's fourth season incorporated elements from the 2013 Disney Film Frozen. It depicted the icy arrival of Elsa played by Georgina Haig after the urn she was confined in was inadvertently drawn into the time travelling portal from the Enchanted Forest in the past and transported to present-day Storybrooke.

In Once Upon A Time Season 4 episode's opening scene, the backstory of Elsa and Anna's parents' death was showed. The episode started off with their mom quickly scrawling a note with "the truth" about Elsa to send back home in a bottle.

The series' casting for the Frozen characters is extremely remarkable.  Georgina Haig as the infamous Ice Queen Elsa, Elizabeth Lail as the ardent Anna, and Scott Michael Foster as the hunk Kristoff, they all exemplify their characters impeccably. In Once Upon A Time's latest season, the only missing in the cast was Olaf but the series presented Elsa's chilling repulsive snowman inflicting chaos on Storybrooke even Kristoff's rock troll grandpoppy made an appearance in a flashback where he gave the sisters some advice.

The series depicted a new twist on Frozen. After reading her mom's diary during wedding planning for Anna, Elsa discerned that she's the cause her parents died. Ostensibly, her parents were frightened of Elsa's powers and were going to Misthaven to find solutions. The revelation prompted Anna to run off alone to the enigmatic town. But as the latest season of Once Upon A Time progresses, we discover that Misthaven is just an alternative name for the Enchanted Forest.

In extant day, Elsa didn't openly mingle with anyone in Storybrooke but she is now intensely entrenched into the town. As pictured in the newspaper, she saw her snowflake necklace and headed to Mr. Gold's shop to find it. Since Anna was last seen wearing it, it's her first hint of her sister's location.

Aside from Elsa's arrival in Once Upon A Time Season 4, Regina had a severe case of the gloom. The once evil royal just can't catch a break in romance and the stroppiest history primer goes down when Robin Hood tries to exchange conversations with Regina, and his not-so-dead wife Marian. The Evil Queen suddenly returned. Her first plan is to go back in time and kill Marian before she can be saved by Emma, but then she had a trivial volte-face. In fact she saved Marian in the forests when the malevolent snowman nearly stamps her. She decided to find the writer of Henry's fairy tale book. As Regina proficiently accentuated, antiheroes never find love, so finding the writer of the curse was her solution to give Marian what she deserves.

In town, the solitary happy couple appeared to be Belle and Mr. Gold, who celebrated their wedding by going to his son's grave. The most stunning and impeccable tribute to Disney's classic transpired when the newlywed couple dances to "Beauty and the Beast" soundtrack in the library.

Meanwhile, in the entire season 4 first episode of Once Upon A Time, Hook and Emma are as bewildering as ever!  Emma was as sizzling and icy as Elsa.

In the interim, Elsa seemed not prepared to freeze Storybrooke over like she fortuitously did with Arendelle. On the other hand with no trolls hanging out in town, if she annihilates someone's heart; there are no sisterly ties to help a person. So let's tune in for the inevitable Regina-Elsa or Rumplestiltskin-Elsa face-off. With Frozen magic on Once Upon A Time Season 4, buoyantly neither of their relationships retains them from clashing out.
