You were on a cross-time dimensional mission and didn’t realize you were a few years in the past from your current timeline.

You run up to Barbara, your, girlfriend, but when you grab her face and kiss her— nope, she pushes you away.

“Hell no!!” Babs yells, you stand there confused.

“You’re supposed to be dead! I saw it happen, and I was respectful but not grieving.” Babs says with and air of surprise and dislike.

Great… Wrong part of the timeline!
