Spoiler alert: Do not read on if you have not yet seen Season 6, Episode 9 of AMC's "Mad Men," titled "The Better Half."

Don Draper's affairs came totally full circle in Sunday night's "The Better Half" episode of "Mad Men." It was visting day at Bobby's camp, and with neither Megan or Henry there for first night of the weekend, one thing led to another and exes Don and Betty ended up in bed together, just like old times.

But this time around, a newly-slim Betty had the upper hand. She claimed she was happy in her current marriage and even sympathized with Megan. “That poor girl. She doesn’t know that loving you is the worst way to get to you,” she whispered. And when Don woke up, he found his ex-wife eating breakfast with her current husband.

The rendezvous was weird, but probably inevitable. BuddyTV found Betty and Don to be surprisingly cordial -- but loved that Betty got to get under Don’s skin a little bit.

Collider agreed, calling the post hook-up diss Betty’s best moment in series history. As TVLine put it, Betty got her groove back.

TV Replay scours the vast television landscape to find the most interesting, amusing, and, on a good day, amazing moments, and delivers them right to your browser.

"Mad Men" airs Sunday nights at 10 p.m. ET on AMC.
