Ian is in the worst possible place atm, he has lost his only daughter, whilst I am not excusing his behaviour at all I do, to some extent, understand why he did what he did - he is very lucky to have a friend like Mick to cover for him, not many friends would do that, but I do feel he needs to explain to the police where he was that night and what he was doing, its all very well Mick covering for him and taking the blame but the truth will come out. I also understand why Ian begged Mick to cover for him, he was right in saying the press will make a field day of it, and they would, Ian needs the press to focus on Lucy and who murdered her and if his indiscretion comes out, that is what the press will focus on
I do sympathise with him but I also do think he needs to come clean, at least to the police and his family
