What happens in the episode Memory Blank in Danny phantom?

Answer 1

In Memory Blank, Danny, Sam, and Tucker receive an invitation to Paulina's Quincenera (Paulina only invited them because she noticed Danny Phantom seems to be around Danny Fenton, so if she wants Danny Phantom to come to her party, she has to invite Danny Fenton and his friends also). Sam, however, decides not to go, and reminds her friends of their earlier plan of spending that evening at the movies. Danny and Tucker finally convince her to go, and when they walk away, Sam says she will go unless something bad happens to Paulina. Meanwhile, Desiree hears and misunderstands her, and sets off to hurt Paulina. Throughout the day, Danny fights off the ghosts Desiree sent, and each time he defeats them, he realizes they each say Sam's name. He becomes suspicious that Sam somehow is involved in the ghosts coming after Paulina, and confronts her. She says she doesn't know anything about it, and they get into a fight. As Sam leaves she says, "Sometimes, Danny, I wish I had never met you!" Desiree hears the "wish", thus wipes Danny and Tucker's memory of ever meeting Sam (Sam remembers since she was wearing the Specter Deflector, thus Desiree's powers didn't reach her). Sam realizes what happened, and tries to get Danny to listen to her. He finally listens to her after some ghosts try to attack Paulina. First, Sam helps him get his powers back (since Sam was the one who persuaded him to go into the ghost portal). She puts the DP emblem she had created earlier in the episode on his chest and tells him to go inside the portal. Danny becomes half ghost again, and they go to attack Desiree. Danny, however, doesn't know how to use his powers or the fenton thermos since he "just" got his powers. Sam realizes that Desiree has to obey all orders, so she wishes things were back to the way they were before, and that no one remembered of this except for Danny, Tucker, and her. Desiree is forced to grant Sam's wish, and everything is back to the way it was. Danny decides not to go to Paulina's Quincenera after all, and keeps his promise of going to the movies with Sam. At the end of the episode, the two share a cute crush moment.
