For me, it was definitely a bad edit, nothing was shown of Joe running to the HOH room and exaggerating Willie's actions. Joe just had to rub it in when Willie came into the HOH, he didn't try to diffuse the situation one iota.
Once again, Joe aggravated the situation when he went downstairs, instead of keeping it cool. I wish Willie had let Joe hit him. and I didn't see 4 head butts. JMO. I think Joe should have been warned as well, I agree with Ugot.
