In short we could have called these two episodes: The Damon Diaries!
In Children of the Damned, we were taken back, waaay back to a time of corsets and waistcoats (1864). And we were made privy to "from whence he came", that is to say: The innocence of Damon Salvatore, before he went all "Grr Argh" vampire.
That episode of TVD (as it is often referred to on Twitter ) was a roller coaster ride of revelations from beginning to end (and yet had still left us with cliffhangers) including: more as to why Anna (Jeremy's "cute stalker chick") wants to find the grimoire almost as badly as Damon does, and why Damon told Stefan (back in the pilot episode): "I promised you an eternity of misery, so I'm just keeping my word."
The Damon of "Then" (1864) was devoted and in love with Katerine, even after knowing that she was a vampire. He was so in love that he was willing to have himself turned to be able to stay with her.
Unlike Stefan, Damon was very perceptive of their father Giuseppe Salvatore and protective of Katherine, and he knew that Giuseppe would not understand nor accept the fact of Katherine's true nature, even if they'd all come to love her.
Hence Damon beseeches Stefan, no matter what, not to disclose anything to their father Giuseppe. But as Stefan reveals, he had "put my fate in my father and Damon put his fate in me and I destroyed that."
And so leads to the first act of betrayal on Damon by Stefan.
The look of hurt that Damon gives Elena on her betrayal could not be hidden. I tell ya, if looks could kill…
Well as if that wasn’t enough, switch to last nights (Thurs. Feb. 11th) episode: Fool Me Once. Just when you thought that Damon would have his “happy ending”, lo and behold we find out that Katherine, the love (and death) of his immortal life – WAS NEVER IN THE TOMB!
Thus by the end of the episode, Damon is left betrayed and bereft. And you wonder why he has trust issues?
It is with regard to all these harrowing happenings over those two episodes, why I can’t help but feel sympathy for Damon.
Yes, true I am already a fan of the D-man – reason being from the beginning that I was a sucker for this bad boy – but now added to that, is also the fact that beneath his "cocky much" exterior, we see there is much more to Damon as he is now, in the present day and moreover WHY he came to be the way he is, i.e. “acting” the bastard.
Stefan may be considered by some the better brother to like, but Damon is by far the rebel with a cause, that cause being - “Love”!
