At Sid (Suraj Sharma) and Hannah's (Ashley Reyes) wedding party at Pemberton's, Sophie (Hilary Duff) recaps her recent experiences. "I blew it with three guys in 48 hours and now I am doing the electric slide," she tells Valentina (Francia Raisa). "I think this is my rock bottom."

Then the show cuts to future Sophie (played by Kim Cattrall), who tells her off-screen son, "I was wrong. Rock bottom wouldn't come until later that year."

In a flash-forward, young Sophie is seen frantically on the phone while driving a car.

"Mom, please call me back. I think I'm dating my mom," she says, just before she accidentally bumps the car in front of her.

As Sophie gets out of her vehicle to assess the damage, viewers can see that the impacted car has a license plate that reads "LGNDRY," an obvious nod to Barney Stinson's often-used word on "How I Met Your Mother."

An irritated Barney emerges from the front seat, wearing a suit (obviously), and says "Dude..." as his bumper falls off.

Back to the future, Sophie's off-screen son asks who it is, and she teases, "We'll get there soon enough."

Fans finally see the full extent of Sophie and Barney's interaction on the mid-season finale, released on Tuesday, March 28.

This marks the second major cast member to appear on the "HIMYM" spin-off series, following Cobie Smulders' return as Robin Scherbatsky on the season one finale.

Singer Meghan Trainor guest stars on episode two as Sophie's upstairs neighbor who experiences early labor.

Regardless, Sophie helps Ramona deliver her baby.
