The truth about Leo

Since his Mum died Leo's dad has changed and gets drunk regularly - Leo tries to cover it up but realises that he must do something to help - but what? Leo's dad has changed. Since Mum died, his drinking is worse and now he's a different person, someone Leo doesn't recognize. The truth is that Leo is covering up for him and when things get bad Leo escapes into his own head, pretending everything's OK.
