Invitation: In order to enter any house owned by humans, they need to be invited in by a person that officially lives there or the person of entitlement. Once invited, the invitation cannot be revoked. If an original vampire lives in a house, other vampires can enter freely and if an original vampire is in the house without being invited in, it will become disoriented and will begin to suffocate.

Vampires don't need invitation to enter other vampires houses...They only need invitation to enter houses of humans.

Ever since the beginning of this season, I've been waiting for Mr Klaus to get violent...I think we are finally getting there. Really nice episode. I just feel one of the originals is going to fall this season. The only hope is if both original brothers stay united.

TVD is officially more interesting...show got a little boring towards the end of last season but with these so called 'flash forwards', the suspense is like wow...The originals is building up as well...it's going to be really explosive soon as this new storyline develops...I fear for the mikaelsons though esp nicklaus.
