What other choice do they have? They fucked up with the actor, found out too late that some fans really liked him with the character of Ciara...and apparently didn't give it much thought when they decided to reform Ben. So unless they re-write history, that's their only avenue.
Besides the carrying & sock dressing, does Portia also get to witness her parents having sex? Because unless Kyle & Maurico are doing mime fucking, there's no way the brat isn't getting an education while sharing their bed.
