Hey everybody, i've just signed in :D But i was just wondering how "Troy" i don't remember his name(the vampire Sage turned) could walk into the Salvatore house, i mean shouldn't he be invited in by Elena, because is actually her who own the house?

in epsiode 18 season 3 where Sage is comming to the Salvatores house to kill Stefan, because of what he did to Finn. There's a little clip where you see Elen trying to run out of the door, but then "Troy" stand in the door blocking. Later Sage is calling on him, and he just steps indside.
