“Two and a Half Men,” always making headlines for some reason or another, will kick off its 12th and last season with an attention-grabbing plot: Walden (Ashton Kutcher) and Alan (Jon Cryer) pretending to be in a relationship, getting hitched and adopting a child.

So says Nina Tassler, the CBS entertainment chairman, speaking to reporters about the sitcom during the summer press tour. Apparently, Walden has some sort of health scare, which propels him to get all freaked out about the true meaning of life and wonder if he should adopt a child. Because that’s a tough task for a single man, he wrangles in Alan to help.

“So once and for all he decides, ‘I’m going to propose to Alan and we’re going to get married and adopt a child as a gay couple,'” Tassler said, via the Hollywood Reporter.

Expecting any backlash? Tassler doesn’t think this storyline will be controversial. “I think it’s a very positive statement that, you know what, I am going to adopt a child as [part of] a gay couple and the reality is, he can do that,” she told the trade paper, adding that the storyline is especially poignant “in a universe where at one point you couldn’t do that.”

Given that in some places, same-sex couples still aren’t allowed to do that, what does GLAAD have to say about this? Although the activist group didn’t want to speculate on a plot that no one has seen, GLAAD President Sarah Kate Ellis did offer a statement about how she hopes the storyline will proceed.

“We hope the show will acknowledge not only the progress made in acceptance of gay and lesbian couples, but also the fact that — in many areas of the country —same-sex couples are often under greater scrutiny or still barred from adoption options that straight couples have,” Ellis said.

“Two and a Half Men” is no stranger to potential controversy, as the series is ending after a chaotic three years that started with the now-infamous Charlie Sheen meltdown. Later, co-star Angus T. Jones left the show after publicly bashing it as “filth” on YouTube.

Although their respective replacements (Kutcher and Amber Tamblyn, playing Charlie’s long-lost daughter) did just fine, CBS decided it was still time for the veteran sitcom to come to an end next year.
