Caroline: How's it going in there? Damon: Dr. Whitmore was working in a battlefield hospital when he discovered Enzo was a vampire, so he drugged him, locked him in a coffin to ship him overseas. Damon: In 1958, after the fire, Enzo was dead, so I had to take on my revenge plan solo

(Katherine is in the safe with Stefan)
Katherine: So try not to be mad at me. I was hoping that maybe you could help me find Wes
Aaron: Yeah. I'll let that person grow up and start a family, and then I'll start killing Whitmore's again. In all fairness, I am the one that abandoned him on a train platform in the middle of World War II
Joseph: Well, there's always time to be a better man
Damon: Eh, not sure I got one of those in me
(Joseph attacks him)
Joseph: Sorry about the vervain, Damon. My name is Enzo See for yourselves
Damon: But on the plus side, that's how Enzo came up with his plan
(Damon and Enzo are back in their cells)
Enzo: Well, the thing about our daily ration of blood is that it's barely enough for one vampire to survive on, but if one vampire were to drink two rations every day for the next year, he'd be able to build up his strength so that by the time new year's Eve comes round again that one vampire will be ready to fight
Damon: Are you sure that will work? Stefan? This little annual shindig is where Dr. Whitmore got to show all of his Augustine friends what he'd found in his research
