Damon woke up in a basement, which had some fire igniting. The last thing he remembered was the pain in his head that had felt like a magical migraine. After the council had found out that vampires were back in town, they'd used the same device used in 1864. Not to mention, John Gilbert was back. He apparently had a ring that helped him cheat death. When that device had been activated, they'd put everyone in the basement whom had collapsed.
He looked around from where he was on the floor. He felt weak, which he knew meant that he'd been injected with vervain. Just enough for a vampire to not be able to move much. After all, vervain weakened vampires. And as he looked, he saw John stake Anna, the daughter of a vampire named Pearl whom he'd cared about and known since 1864. He hadn't been there to stop John from staking Pearl. Now, he couldn't save Anna, because he was weak.
Kat was walking around the grounds, searching for Damon. She knew what John had been planning, so she hoped he hadn't gotten Damon. She was worried that Damon was in danger, because she couldn't get a hold of him. And she didn't want anything to happen to him.
After a few minutes of walking around in search of him, she saw a small building that looked like maybe there was a fire below. Since she knew that John's idea was to burn the vampires, she was afraid of what the fire was. She didn't let it consume her, though. Instead, she rushed over to it and headed down the stairs.
When she got to the bottom, she saw that it was an old basement. There were a lot of people, mostly desiccated vampires or dead humans that were thought of to be vampires. She knew one desiccated vampire as Anna, since she'd gotten to know both Anna and Pearl. Then, when she looked around, she finally saw Damon. That's when she rushed over to him, which was when she saw that he was weak. That made her realize that the vampires had all been injected with vervain after being found by the council to possibly be vampires. Since he was weak, she put an arm around him, helping him.
"Come on. Let's get you out of here," she said.
Damon was glad for the rescue, especially from Katherine, and helped her help him get out of the basement. He then let her take him home, since he was still weak. Digesting vervain when drinking Bourbon was one thing. Being injected with vervain was another story. However, he eventually felt better after having a hospital bag of human blood.
