Exorcism (For those sticking around after the rescue)
Spike was feeling pretty damned confident about himself; they had the demon in check, the trap was ready, and Pike wasn't lying on the floor in a crumpled, bloody, very dead mess. All was good with the world. At least, all had been good with the world up until the skanky hellbitch decided to pin Andrea up like a pinata at a birthday party. Spike's eyes snapped toward the demon dangerously, every instinct of his telling him to rip her head off in the most literal way possible. Naturally, that'd be a bad thing for Faith. But at least it'd make him feel better and spare Andrea from a death that he wasn't terribly interested in witnessing. Ever. Not because he actually cared about her or anything, but because it'd be a pitiful way to go out. Being choked to death by a demon was uncool. There was no grand, heroic exit. It was just pinned, choked, done. Nothing special. He'd have pitied her. See? Spike didn't care. He was just being realistic. Andrea. The Girl Who Choked and Died. Sad story.
From the other side of Faith's body, Spike was able to hear Pike starting on with the Latin. He knew how the demons got when the exorcisms started because he had seen it happen before. They'd flail around, shout out, and try to get out of the hold of the religious chant as quickly as possible. That was why Spike knew he needed to latch onto the demon tighter, using his strength to shove her around and toward the open door ahead. Using that vampire strength of his to an advantage, Spike hefted Faith up and shoved her into the next room. The trap that they had set up previously was lying in wait there, along with the Winchester giant and the tax accountant with wings. If his throw wasn't good enough to get the demon where it needed to be, then Spike hoped that the two on the other side of that door were ready to up and finish the job for them.
As soon as the body was out of his hands, Spike looked to the wall where Andrea had been thrown. He wasn't worried about her being strangled to death still or anything. He just wanted to make sure that there wasn't a body for him to haul out of here when this was all over with. That was all. Really.
