A door alarm wakes Y/N at four in the morning, and she investigates with a bat, only to find a shadowy figure in the living room. Acting on instinct, she attacks and tackles him, causing a commotion that brings the rest of the team rushing in. When the lights come on, Steve stops her and explains the man isn’t an intruder. As he stands, clearly shaken but intrigued, his intense stare makes it clear this violent first meeting is only the beginning.
