What did Stefan mean when he a dit "Actually she's doing this to me." When he and Elena are talking about why Katherine turned Caroline into a vampire. I just watched the episode again today and I'm trying to make sense of what he meant par saying that.

I understood it as she did it to get to Stefan, screw with his mind and hurt Elena at the same time.

I didn't understand either.... Katherine turned Caroline to hurt Stefan? It's obviously weird and bizarre but I think what he mean was that she turned Caroline to hurt Elena and when Elena is hurt the one who is hurt too is him so.. It's strange.. But hey, maybe katherine support Staroline hahahaha kidding!

Because Caroline is Stefan's friend, so if Katherine turn her into a vampire, that hurts Stefan because he don't want that for her

i think deep down he knows kat has/had a thing for hm n b/c he is w/elena n that bothers her 2-01 she want 2 punish him par hurting any1 who is close to him ou to elena
