Plus I have been to a few weddings in the past and I've seeing a lot of people getting drunk too and no one cares! If you are going to comment on a JaSam scene check your facts first before you make a totally bias comment!
Maybe if you were paying attention this was a little after she lost her baby so she got carried away by drinking, since most of those people knew about it I think they would understand! I am sorry that you think that everybody on the show needs to be so perfect like little miss Liz then don't watch a soap opera!
