Do you think Wellsobard was always conscious of his grand plan in those 15 years?

I mean, having to pretend that you're literally someone else all the time must've been difficult. I like to imagine that on some days he wakes up in the morning forgetting that he's not actually Wells, and had to sort of mentally restrain himself from getting attached to that life. And also there's that line from a deleted scene where he said he actually has real Wells' thoughts, memories, etc. I just thought it's kinda interesting to think about
