Klaus regretted it the second he saw the sadness and emptiness fall into Stefan's eyes. Klaus released him from his grip as Stefan slide down to the floor. "No, no, no, no,…" Stefan kept repeating as he dropped onto the floor. Everything was coming back to him. He tried to fight the compulsion but it fought right back forcing him to feel everything. It was like his mind was being torn apart from all of he emotions.
First thing he felt anger at Klaus for forcing him to feel again then it just turned into pain and regret. He thought about how he had drained the life from so many people and regret and empathy filled his mind. He killed all those people. He couldn't even blame it on Klaus this time, it was all him. He was a monster. Then the realization of Damon leaving him forever caused all the other emotions to go away temporally but only left him with feeling pure darkness which seemed to be worse than everything combined. It was the same feeling that Stefan had felt when he stood in the real world watching as Damon never crossed the threshold from the other side but now it was worse because whatever hope of bringing him back was gone. "Stefan?" He heard Klaus's voice and looked up at the hybrid realizing that Klaus had been standing there the whole time. He didn't want to be seen falling apart like this especially by Klaus. He didn't want for him to watch him fall apart.
He ran upstairs with vampire speed past Klaus into one of the spare rooms and shut the door behind him breaking off the second half of the door knob and throwing it at some vase at the other side of the room. Stefan tried foucsing on his breathing before he tore the entire room apart. It wasn't exactly working though as he took one the small tables near him and threw it towards the wall watching it break into a million pieces. He didn't know what to do. He wanted to die. Everyone in his life is either dead or gone and he is responsible for the deaths of more people than he can count. He didn't have a reason to keep living his immortal life anymore. He needed his brother to be there to help him. He said he would be there to pull him out if he ever went over the edge but now Damon was gone forever. Even Damon's death was his fault. Damon would have never been on the other side in the first place if he wasn't trying to get Stefan out.
He sat in the conner of the room looking at the mess around the room. Every part of him felt like it was breaking into tiny pieces just like broken table he had recently threw. He had been through this twice, he probably should know how to handle flipping his humanity back on but for some reason it only was worse each time it happened. He used to focus his emotions on one feeling but this time there was nothing to focus on. There was no one to blame because it was all his fault. Tears started stinging his eyes for the first time in what was probably 100 years as he heard the door open and Klaus walked in.
"Please leave me alone.", Stefan begged. Klaus never thought he would see Stefan so broken apart. He looked vulnerable and lost. Most of the time that he had known Stefan he had been a heartless vampire even when he turned his humanity on he just got angry and wanted revenge but he never was really broken or a least never showed it. Now Stefan was sitting in the conner of the room tears running down his face looking like he was trapped in hell.
Klaus walked slightly closer to him. "I didn't want for you to have to go through this." Stefan's veins under his eyes stood out along with his fangs. "Get the hell out of here!" "You don't deserve to go through this alone love." Klaus walked next to Stefan sat on his knees across from him. "I deserve so much worse than this. Do those human lives that are gone because of me mean literally nothing to you?", Stefan yelled! "You're a vampire Stefan, it's your instinct to kill. It's how it was meant to be. That doesn't make it your fault.", Klaus said, as he wiped away the tears from below Stefan's red eyes. "I still killed them. They were living people! They had emotions and lives and now they're died, just like my brother!"
"Klaus looked into Stefan's hopeless eyes. He had to say something to fix this. Maybe he could ask Davina if she could find Damon and bring him back. It was worth a chance if it meant he could give Stefan hope again. "We can still try and find Damon. The witches are much more powerful than you would think." Stefan looked up processing what he just heard. There was chance even, if he wasn't sure if he should believe Klaus, there was still a chance. "The other side is gone though how can we pull someone out of what ever comes after?" "Maybe they went somewhere else. Bonnie had many witch ancestors, its possible they protected her and Damon. I know a witch that could find out."
Stefan nodded while climbing out of his sitting position along with Klaus standing up next to him. "We should hurry incase there is a time limit on what ever the witches could have done.", Stefan said as he followed Klaus towards the door. He didn't allow himself to think about anything but Damon. He needed to know that his brother was safe.
