ok- so she could have just been zoning out and it was editing them out to have her hear a voice and "zone"- not different times in that scene, no flashback, etc.
Or- it was a flashback. But- which was the flashback?
-She flashbacked to an earlier time when it was just her and two coffin fulls of nitro that she handled on her own (Killing Lawrence, no other host like william, etc) and she couldnt complete her mission because she was reset because she had no host to accompany her. Now (30 years ago) she has a host in william that shes using to help her complete the task (that she ultimately won't complete). God that sounds so ridiculous to type. lol
Or
-We are seeing two time frames in that scene. One with her after she grabbed a couple coffins full of nitro in the present, and one with william/lawrence 30 years ago.
I'm actually more inclined to believe she was having a flashback 30 years ago (so lets call it 30 years and a month w/o william, and 30 years with william)
Regardless, I think we see that storyline play out next week.
