If I had listened to the signs this never would have happened. I was selfish and I altered your true fate, and I will make it right...for your sake and your daughter's. I love you, Tommy. Thank you for giving me the chance to make my last life count.
This is the relationship between Tommy Cole and Wendy Beauchamp. They got off on the wrong foot, in Season 2, when they both fought for the same book in the library. They later see each other when someone is injured. She finds out that he is a paramedic. They meet each other at basic community functions, by chance, and began to fall for each other. They begin dating, but Wendy feels that the universe is working against them. In Sex, Lies, and Birthday Cake, Tommy finds out accidentally that she is a witch. She was supposed to spell him to forget her (as Joanna instructed her to do), but she couldn't because she is falling in love with him. When Wendy's father's soul was transferred from Frederick's body to Tommy's body, he entered a dormant-like stage. Wendy then said her heartbreaking goodbye before they performed a spell that brought the king back. Tommy is dead because of Tarkoff's sinister ways of trying to bring back the king. Overall, because King Nikolaus is back, Tommy is now dead for good.
However, after the King was succesfully killed, Wendy gave up her last life so that Tommy could come back to life and be with his daughter. When Tommy wakes up and realizes that Wendy is dead, he feels devastated and cries while holding her dead body in his arms.
