he was helping you guys get back to the past when you got stuck there to save the world,he had a thing for you but you just keep rejecting him,and when you did he accidentally got transported after you guys did,he accidentally got himself arrested and you came to pick him up and now your two are in the shield base picking up some things for Jemma’s experiments,he found something orange scented like a spray or smth and sprayed it and sniffed it “that Is amazing!” he was exited because since he was basically from a dystopian future he never got to experience any of this at all,he then stupidly sprayed it in his mouth not knowing what would happen,you turned around from putting things in the shopping cart thing shield had for some reason.right as he did it you turned around again
