What Abendroth was rambling was out of context at best, but to a person who already believed the kid to be a killer it did seem like a confession. A confession that appeared to mean he hadn't meant to kill his mother, but had, accidentally. Did that mean he had meant to kill his father and his mother walked in at the wrong time? Or was he talking about the monster and Francis was assuming too much? Somehow, he didn't think it was the latter. Abendroth had been so detached in his home, and it wasn't far-fetched to assume his guilt had conjured up some distorted image of his mother. If the kid could do that, then he could definitely have created some other monster to kill his father.
The problem with it all was that if the monster was somehow connected to the teen's powers, and Francis was almost positive it was, he obviously couldn't control them entirely. If he could, he wouldn't have been tormented by the apparition (assuming that's what it was) to the point he couldn't stand on his own anymore. Did Abendroth have enough control over his power to summon it intentionally to kill his own father?
As the kid sagged to the ground, Francis went with him. He was crouching, gripping Abendroth's arms, and it was awkward. Francis didn't want to stay that way, feeling an unpleasant prickling sensation on the back of his neck as he thought about how vulnerable they both were. Even if it wouldn't make a bit of difference logically, all he wanted was for his back to be pressed up against something, not facing his empty living room.
All things considered (his drunkenness for one, and Abendroth's inability to support himself for another), it was relatively easy for Francis to pick himself back up again and bring the boy up with him. An arm around Abendroth's waist and a fistful of the kid's shirt seemed to do the trick – at least well enough for Francis to get him to the couch. It all was a bit of a blur for him; his mind was elsewhere, but suffice it to say they both ended up sitting on the couch, facing the blank flat screen TV on the opposite wall.
"That wasn't real," Francis finally said. "Aben-- Dietre ... dead people can't do that. Can't come here. Just … next time, tell her to go away the same way you brought her here."
