They had averted the apocalypse.
Or, really, they had averted this apocalypse, which was experienced by Five, and which the Commission had been determined to see happen at the hands of Vanya.
Allison had bundled Vanya up in a cloud of cashmere and chanel and whisked her off to LA, unwilling to remain away from her daughter and even less willing to leave Vanya in the hands of any of her 'emotionally constipated, idiot brothers'.
Luther had wanted to go with them, but Allison only let him come on the understanding that he couldn't live with her and Vanya yet. He had betrayed Vanya terribly and that would take time to heal.
With Luther, Allison and Vanya gone, about ninety percent of the horrendous tension left with them. Ben was dead and couldn't feel anything, but even he had felt the constant tension of walking on eggshells.
And it left the four of them in the house.
Sir was dead (still) and hadn't bothered with trying to haunt Klaus (yay), which meant that there was no real reason to avoid the old house, aside from years of trauma and nightmares, which had never been enough to stop any of them doing anything.
Klaus moved back into his room. Diego moved back into his. Five moved into another room, well away from everyone else because he was trying to learn to how to be a person but it was a long, slow process and he needed space and quiet more than the rest of them.
Ben... was still dead.
But since they were doing this thing, Ben decided to start where his nightmares were oriented.
The cellar. Not Vanya's basement, but the old, converted cellar, where it was always cool and damp and there was no possibility of bringing down a building if They got out.
Which was why, some half an hour later, there was the terrifying, inhuman shrieking of the Horror having been unleashed. And, even more strangely, it was a scream that echoed as ripples through the spirit plane, ghosts fleeing and energy twisting, centred back down on that cellar.
