I think Sockness was the one who wrote up that entire chatlog, RPing as Magi-Chan.
Magi-Chan calls it the "dimensional merger" but only Sockness calls it that, Chris calls it the dimensional merge. This line is also something Chris wouldn't say since he believes characters are real and independent of creators:
"Magi-Chan: You created Jakoba. You can threaten to revise his character."
So I guess hubby is supposed to refer to Chris, but is an error on Sockness's part.
It's fucked up that Chris actually believes that conversation really happened between Magi-Chan and Sockness. In the chatlog, Sockness dangles the Merge over Chris's head and threatens to stop it unless he and Chris meet. And gets Magi-Chan to say adding Jacob to the marriage is a great idea:
"Magi-Chan: If we work together, I can open my wife to adding you to the marriage."
