Sorry but I don't think so..... it's THE domanda =s I don't know,for me it's più in 1x11 not pretty sure but this scene mostra verry well that Damon has a feelings for Elena I think.... :
I think in the epi ,,Monster´´ he fell in Amore with her cuz she was so strong and had courage to hit him xD because he tried to manipulate her and than it doesn't worked. ive was sure when he was in her bedromm and touches her chest :) it was soo sweet!
Its hard 2 tell cuz when he met her he was still in luv with kat. It must've been really messed up with him,i think he luved her from 1st sight but realized it after he started 2 let go of kat n that was in the 5 last episodes of s1
