Pain is a constant.
Something that, disturbingly enough, is what Peter is getting used to- and this happened to be something that terrified him greatly.
People avoided pain. Pain is a warning sign that something is not right- abort the mission, back away, let go, run far as you can… but Peter doesn't have that option. There is no escaping, there is no letting go, there was no chance of running away (oh, how wished that was not true).
Pain is his constant- his new normal, his reality. And nothing can change that.
A/N: The title comes from T.S. Elliot's "Four Quartets 1: Burnt Norton."
