I didn’t have much of a liking for Tamara on Once Upon a Time.
We first think she’s nothing more than Neal Cassidy’s fiancee. Though that did crush any dreams for Emma Swan and Neal to get back together and make a perfect family for Henry.
But in truth, her real love was Greg Mendell. Who was really Owen Flynn, one of the few “outsiders” to Storybrooke. For different reasons, they both wanted to destroy magic.
So much so that Tamara tries to kill Neal when he tries to stop her after all the truths becomes known. Everyone believes Neal was killed by her but he survived.
Greg and Tamara take Henry by force and deliver him to the Lost Boys of Neverland. But they didn’t realize that they were just pawns. Peter Pan didn’t want to destroy magic, he wanted Henry’s heart to keep his youth/power/immortality.
She is found dying by an arrow and is healed by Rumpelstiltskin. The Dark One hears what she has to say, and he rips her heart out and crushes it for what she did to his son. I don’t think many fans were crying about that one.
