On Two and a Half Men Season 12 Episode 2, we picked up not long after Alan and Walden's surprise gay marriage proposal on the final season premiere.
If you missed it, Walden convinces Alan to marry him so he has a better chance at adopting a baby, setting the stage for the sitcom's huge gay sendoff.
Walden, we're reminded again on Two and a Half Men Season 12 Episode 2, wants to leave a legacy in this world but just can't find the right woman.
What he can find is a great "husband" in Alan.
Alan has nine out of ten qualities that Walden is looking for (you can do the math on the missing 10th), which isn't a surprise since they are best friends.
Really, why haven't more single bros desperate to adopt babies alone thought of this incredible faux gay workaround? It begs the question, that's for sure.
Not that there aren't some snags, even in this near perfect relationship. Alan wants a destination wedding, while Walden just wants a courthouse ceremony.
Also, Alan is offended when Walden asks to get a pre-nuptial agreement, which is probably just in this (or any) billionaire's DNA at this point in life.
