The Future is Emerald Green

Villian touches Bakugo while in a fight and it brings his future self of ten years into the current year. He's impressed with himself until he calls Deku 'baby' right in front of his boyfriend Kirishima. The redhead is mad at him as they watch the older version of himself flirt and be so touchy with the greenette without any explanation as to why. When they're alone finally, the future Bakugo tells current Bakugo exactly why he treats the two completely different, and it makes him wish he never found out.
