The new headcanon is that Junkrat has never seen D.Va outside her mech and believes she’s an omnic who ate a teenage girl
He sees her mech start blowing up and she pops out and he’s like “phew thank god that lil sheila got free of that tin can before it blew up” and then another one falls from the sky five seconds later and scoops her back up and he LOSES HIS SHIT
