Kol: (to other ghosts) Welcome back. It was our deaths that allowed this day to come to pass. Massacres performed in the name of resurrecting the immortal Silas. Twelve hybrids, twelve witches, the slaughter of innocents by the so-called hero protectors of Mystic Falls. They risked unleashing hell on earth for their own selfish gains. And today, that's exactly what they're going to get.
