A blast from the past

Just before their lips met, a hole opened in space... a black tear in the fabric of reality... and out of the hole in space jumped a suprisingly spry 70 year old woman... with a magic wand... "Stop RIGHT there..." The newly female Jon recognized the face and was shocked... "GRANDMA?!" And as the woman morphed herself younger, with a glow of her wand... 70... 60... 50... 40... ever so briefly, she became an old man that Jon recognized even more and said... "You're close, Johnny... you're very close."
