Even if she threw the drink. I dont believe she deserved to be left with a bruised face. It wasnt like he pushed her away or anything. He got her down on the floor and 'beat her' He didnt just retaliate once. Why didnt he just walk away? Or call secrurity? Even if she is annoying/horrible no one deserves that at all.
Tho I dont think they should be in there own shows, they should have time to grieve and just be aroun dtheir family.
