The finale of Hawkeye dropped on Disney+ today, and it had a pretty big reveal involving Laura Barton (Linda Cardellini). Hawkeye/Clint Barton’s (Jeremy Renner) wife first appeared in the Marvel Cinematic Universe in Avengers: Age of Ultron when Earth’s Mightiest Heroes went to the Barton family’s house after they needed a place to regroup. Since then, Cardellini also appeared in Avengers: Endgame when the family was snapped by Thanos, and fans were thrilled when it was confirmed she’d be returning for Hawkeye. Warning: Hawkeye finale spoilers ahead! In the Hawkeye finale, it was revealed that the watch Clint had been trying to recover had belonged to Laura, and it was engraved with a SHIELD symbol and a “19,” which implies that she is Agent 19 AKA Mockingbird. After this reveal, one Marvel fan took to Twitter to point out a connection to Ultron.
