I was pretty pissed when I realized it it was Katherine,not Elena he was kissing at the end of Founders Day but I got over it so I suppose I'd do the same with this one but this time it was real and this time it WAS Elena and SHE was kissing him!
Id feel ripped off as a loyal Delena fan if it ended up being Katherine, Damon thinking it was Katherine, his hallucinations of Elena or Katherine, etc. Nope this one is real. Time for Elena to begin denial/struggle/acceptance of her feelings. =)
