you were talking to Deku, but Bakugo was eavesdropping,he was silently being jealous,then...he heard you say "I love cats their my favorite thing in the whole wide world!" He suddenly gets cat ears and a cat tail,he blinks confused and grins,he picks you up and runs away with you in his arms

"MEOW MEOW BITCH"

Bakugo says to Deku before running away
