Nope, that wouldn't explain how Jamie got hurt while in the safe area. That's the real him.A area that imitates where you live but deserted, with creep additions like the shoe left in blood, Yeah no this floor reeks of phycological attacks. I highly doubt that is him, much more likely its this floor messing with them. Though with the whole teleporting thing it is at least posable its him, but yeah readers are sick of him already, the slow release dragging this out makes it much worse.
That's not really a counter to what I said, as I didn't discount that it could be him, just that I thought it more likely to not be. But also it sounds like you know it is, which makes what you said a spoiler. Speculating and taking guesses is part of the fun of reading a series as it comes out. So you very rudely just ruined that for me as now I cant speculate if there was a twist. There was other options like that running to there reopened a wound or failed to close it and she had no option but to try to get out and get help.Nope, that wouldn't explain how Jamie got hurt while in the safe area.
