Walden will meet up with other adoptive dads in the next all-new episode of "Two and a Half Men" this Thursday.

Last week, Walden and Alan came really close to losing custody of their foster child, Louis, after their social worker discovered that they are not really gay. The incident occurred when Ms. McMartin made a surprise visit to their home and caught Walden and Laurel with their pants down--literally. She then became angry because they lied to her and put her job in jeopardy.

At the end of the episode, Walden tried to convince Ms. McMartin to let them keep Louis, arguing that he and Alan were excellent parents, best friends and legally married. They only thing they don't do together is have sex, he said. Eventually, Ms. McMartin allowed them to keep Louis, reports Entertainment Weekly.

A preview of the upcoming episode, "For Whom the Booty Calls," reveals that Walden will decide to meet up with other men who are also adoptive fathers.

According to AceShowBiz.com, the official synopsis states that: "Walden joins a group for adoptive fathers, and finds it to be a nice escape from Alan."

"Two and a Half Men" co-creator Chuck Lorre also recently hinted that the former star of the show, Charlie Sheen, may return for the series finale next month. Back in 2011, Sheen was fired from the show after he and Lorre had an ugly public fallout. In turn, Sheen filed a lawsuit against Lorre, Warner Bros. and CBS. He was then replaced with actor Ashton Kutcher.

Although Lorre has not confirmed speculation that Sheen will be featured in the one-hour finale, Lorre said fans will be "very pleased" with it during the Television Critics Association's winter press tour last Thursday, reports Entertainment Weekly.

Lorre also suggested that the finale will honor the show's past and the success during Sheen's eight year run.

"It would be inappropriate to not acknowledge the extraordinary success we had with Charlie and how grateful I am, we all are, to his contributions," said the show runner. "And there's nothing but great feelings for the eight-and-a-half years we worked together. But how to wrap the show up? It's tricky. It's a sticky wicket. Because in a way, the show morphed into something else entirely for the last four years-and it's something we love-and we want to honor both. How to honor both is the challenge of this finale. And the other challenge is how to get people to watch it without telling them what it is."

When asked if time has healed his "wounds" from his tiff with Sheen, Lorre responded saying, "There are no wounds," he said, despite the fact that hasn't personally spoken the actor for years.

"What happened, happened. And I'm grateful for the time we enjoyed working together and I'm very grateful Ashton came along and kept the lights on. What do I got to complain about? I'm so blessed."

"I'm very proud of what we did here with Charlie, I'm very proud of those shows," Lorre said. "I watch some of those shows and I'm so proud - because you forget, it was a long time ago ... [and] to end the show appropriately you literally have to end two incarnations of Two and a Half Men and bring together a lot of threads. I didn't want to end it without acknowledging the past. I think we did that in a way that will be funny. [What's important is that the show] always goes back to that - that people will laugh and [say], 'Did they really do that?'"

"Two and a Half Men" Season 12, Episode 11, "For Whom the Booty Calls," airs on Thursday, Jan. 22, at 8 p.m. ET on CBS.
