From Gerard's own evidence, he was, as he put it, forced to tell his family of the affair with Ms McHugh. Not just the original event but the ongoing event.. his take on it was the police told the media, so he had to tell the goggleminded family all about it.
Which must have been why Nige then decided to use his phone, as per the police phone tap , to spot him ringing Toni for Gerard to keep in contact..
So when Olivia doodles out to tell us all that Allison needed to be returned, was suffering from depression, etc.. she already knows about the long term exploits of Gerard and the ongoing and current , extremely current and assisted affair between Gerard and Toni.. she knows about the financial chaos as well.
But she tells us all he is innocent, that he loves Allison, so the word 'innocent' is disingenuous , if I was inclined to generosity, or totally disinformative, and deliberately so.. that's if I was being the real me.
so no free pass for Olivia on that score..
