When they go to rescue him, Stefan isn't there. Instead, a very powerful witch (Qyetsiyah) had opened the safe for him and fried his brain due to which he suffers from amnesia. Qyetsiyah (or Tessa) loved Silas but on the day of their marriage, he cheated on her and took the immortality spell for the women he actually loved, Amara, the original doppelgänger of Elena. Stefan returns to his old ways but when he saves Elena from Tessa, she wants revenge so he gives Stefan his memories back which gives Stefan Hallucinations of the safe. Caroline tries to help him but when that doesn't work, Katherine comes back in the picture and manages to cure Stefan but they have a one-night stand, which leads Katherine to believe that Stefan still loves her, however he rejects her. Later on, Katherine takes over Elena's body and breaks up with Damon so that she can get Stefan. After trying to woo him and failing, Stefan realises that Katherine is pretending to be Elena and Elena is with Nadia, Katherine's daughter. They rescue her somehow by killing Katherine and sending her to some sort of hell. Then Stefan volunteers himself to the travellers to give his blood as they needed doppelganger blood. Caroline and Enzo try to find and kill Tom Avery, Stefan's last doppelganger in order to save Stefan and they succeed due to which Stefan and Caroline grow even closer. Near the end of the season, Stefan and Elena keep seeing dreams of the two being together and of them as humans. They work out that the travellers planted those dreams there as it was always meant to be Stefan and Elena not Damon and Elena. Through the fight, Stefan and Elena are kidnapped by the travellers as they need their blood to finish their spell. However, Enzo and Caroline save them by killing Tom Avery, Stefan's doppelgänger. In 5x21, Stefan tries to save Caroline's life from Tyler (while a passenger, Julian, is in his body), during which Tyler kills him, sending him to the disintegrating Other Side. In the episode 'Home' he is Resseructed because Liv did a spell due to which he and his other friends can get back but Damon and Bonnie are left there leaving everyone broken.", "aroline save them by killing Tom Avery, Stefan's doppelgänger.
