I think totally people missed the whole point of the Eddy/Chavo deal.
The backstage thing, Eddy was all mad at Chavo for slapping him. Angle said that he entered the Royal Rumble for his country (Eddy laughs) and Eddy entered for himself because hes selfish. Eddy gets mad because Angle interfered between him and Chavo. Angle keeps mentioning that Chavo is his family, but Angle isn't his family and he shouldn't interfere in their problems. Angle says the problem is traditional American family values and tells Eddy to look in the mirror for the problem..
I think, and I could be wrong, that Eddy is the one getting the heel turn, not Chavo..
