Only the jobber trio can be conceived the least bit as faces. Otunga and Show left the sinking ship like the opportunist bitches they are, and Ziggler kissed Vickie (after being booked as a face in his match... meh).
I want to laugh at you OP, but this is probably what all the little kid audience are confused about at the same moment. but an act that benefits a face, done by a heel, isn't a face turn. a heel has to save a face or get annihilated by another heel to turn face (or take a vacation until everyone forgets him like christian).
Otunga and Bigshow in fact are more heel since they turned on a heel. Epico & Primo, like said above, are just not face. Dolph & Swagger, maybe swagger will become a face jobber.
Primo/Epico/Rosa are really the only ones you could consider a face turn last night, Show and Tounga are still clearly heel and Ziggler kissed Vickie who is the biggest heat magnent on the show, now that Big Johnny is gone.
Just to add to this, Big Shows motivation was simply that he no longer needs Laurinaitis due to the cast iron contract, so he didn't care what Cena did to him. Heels dont always have to like other heels.
