After a brief hiatus, "Two and a Half Men" is scheduled to return with an all-new episode on Feb. 27, featuring the next chapter in Alan and Lyndsey's relationship.

In the upcoming episode, entitled "Cab Fare and a Bottle of Penicillin," Alan will present Lyndsey with an ultimatum, while Jenny becomes weary of her relationship with Brooke.

According to BroadwayWorld, the official synopsis states, "Alan gives Lyndsey the option of choosing between him and Larry. Meanwhile, Jenny fears she and Brooke are growing apart."

CarterMatt predicts that Alan and Lyndsey's love story won't come to an end just yet since another alum from "According to Jim" will join Courtney Thorne-Smith on the show as another possible Alan love interest.

Guest stars in Episode 15 include Melissa Denton playing Amy and David Grant Wright as John, reports Hollywood Hills.

The premise of the popular comedy series is based on the many adventures of roommates Walden Schmidt and Alan Harper. After Walden's girlfriend rejects his marriage proposal, Walden's thrown back into the dating world and has a threesome with Alan and his girlfriend, Lyndsey. However, he then creates a false identity in order to find a girl who isn't after his money.

Alan's son Jake fell so head-over-heels for Walden's old friend Missy when she came to visit that he went AWOL from the Army. The crew may have thought things were going to slow down once he was transferred to Japan, but they were proven wrong.

"Two and a Half Men" S11E15, "Cab Fare and a Bottle of Penicillin," airs on Thursday, Feb. 27 at 9:30 p.m. on CBS.
