Uncrowned's biggest takeaways from a wild night in London after AEW captured the largest crowd ever for a pro-wrestling event at the O2 Arena.

AEW returned to pay-per-view Sunday with its annual co-promoted pay-per-view featuring stars from New Japan Pro-Wrestling, Forbidden Door.

Wardlow made his triumphant return and immediately put the AEW locker room on notice with a vicious attack. Wardlow appeared after Kazuchika Okada retained his AEW Unified Championship against Swerve Strickland.
