>>213070127because you can't really share a reality with someone who has "Hitler survived WWII" in his past timeline, too many deviations.
Insignifiants shit like dolly's braces (she had it 100% in my past), they pose no problems until you confront that exact souvenir with someone. at this point, one of the guys has to shift realities.
and for your information, shifting to different timelines is not something exceptional, you do it all the time, and by "all the time" i mean all the time, you just aren't aware of it.
