i totally agree with this, the smirk on calebs his face said it all. If he wanted to kill him, he would have the first two times when eh slipped. Also notice there was no destruction to the wheel, had caleb fell - it would have damaged the build. I dont understand why loomis nearly commits suicide. Scene before electricity comes on, loomis edge towards the cliff.
I guess the real question is, do Ann and Loomis get together in the end? eventually? too much history and bad blood now
