"Two and a Half Men" finally returned from its winter hiatus and is getting closer to its series finale.

In the last episode, titled "Bouncy, Bouncy, Bouncy, Lyndsey," both Walden and Alan faced challenges in their love life as Alan's friend slept with his ex-girlfriend, and Walden tried to hook up with Laurel.

Alan's plan to prevent his friend Herb from dating his ex-girlfriend Lyndsey backfired after he gave them both a warning. However, instead of taking heed to Alan, Lyndsey and Herb's attraction to one another intensified and they ended up hooking up to Alan's dismay, reports Entertainment Weekly.

Meanwhile, Walden was too nervous to sleep with Laurel while his adoptive son Louis and Laurel's daughter were on a playdate at his house. As a result, they planned to get together on a later occasion at a hotel, where they checked in as Mr. and Mrs. "Aredoingit."

While in their hotel room, the two began making out, however they then got into a tiff when Laurel told him that her daughter said that Louis doesn't like to share. Walden immediately became defensive of his son and accused Laurel of lying. In turn, Laurel became angry and threatened to leave. Eventually, the two end up having angry sex with each other.

A preview of the next episode, which is titled "Here I Come, Pants!" reveals that the social worker will find out that Alan and Walden are not really gay. This will jeopardize their adoption of Louis.

According to AceShowBiz.com, the synopsis reads as follows:

"Alan takes it upon himself to help Walden keep Louis after the social worker discovers he and Walden are not really a gay couple, on 'Two And A Half Men.'"

Season 12, Episode 10 of "Two and a Half Men," "Here I Come, Pants!" will air on Thursday, Jan. 15 on CBS.
