It never happened.
(A blip in time, a might have been, a maybe chance of a ghost. An alternate timeline where everything collided with purple bruises and insurance and generally a banged up job of trying to get the car fender undented. But the car fender was never dented, because don't you see? Time collided, and then erased the collision from everywhere.)
It always happened.

(later, he'll take her ice skating)
