Where was apocalypse?
So where was apocalypse during the future when the sentinals ruled the world?
Since he has been alive for thousands of years?
sleeping most likely. when apocalypse is not around/inactive its because he is sleeping to recharge his body. he wakes up at different points in time depending on the events going on in the outside world. because days of future past is an alternate timeline, for whatever reason he slept thru that period of time and didnt wake. but in the new timeline where the events of days of future past never happen, for some reason he decides to wake up during this time.
