After Tom overdid it by drinking his Smirnoff, he got drunk (as he almost always ends up). Edd was shopping (and it probably took forever because he was filling his shopping cart with Cola). Matt locked himself in his room and refused to take care of Tom because every time he took care of him he vomited on him. So, it was your turn to take care of him.

Tom was babbling like a fool, with the empty Smirnoff bottle in his hand and was lying face down on the couch.
