Coming back to this so many months later, I do find this moment of the interview to be very revealing
"I know that all that stuff looks bad, but it's just crazy that that stuff's even a part of this. I mean it's crazy how that stuff ironically is part of this. It just makes no sense. To me. Like why would God allow pieces like that, that have to be answered in this situation"
In the proceeding conversation before this moment BM concedes that SM would be communicating with her phone if she was able to on Saturday night.
Barry said "yeah" shrugs his shoulders and looks down
But Jonny when you say that, that makes it l... , that makes me look like the bad guy
Like you can see the lightbulb turning on in a very dim room here.
He thought it was one way, then it was the other way.
Confronted with the chipmunk story and the left turn on top of this Barry starts moaning about 'the stuff".
This is fascinating to me, because he clearly gives up trying to account for any of it. He never was going to confess to it, though they nearly did trap him with the 'you were just a betrayed man trying to save your marriage thing".
This is the moment he realises that its not going to work. I'd love to know exactly how he understands the word "ironic" because that is a very interesting word to throw in there - he repeated the whole sentence just to put ironic in there as his main point. "Coincidence?" "unexpected?" In any case, he is saying it is ironic to him. Why is that? Why is it ironic? Because he made those things up as throwaway things so can't account for them?
What i do take from it however, is that he wants Grusing to believe, that he, Barry, the guy who was there on Saturday is awfully confused just like the agents. In fact only God can explain this! Barry is the victim!
And then the killer moment
"If she's (pause) going through this, all this stuff I found out since January. And maybe God wanted to protect the girls from heartache. I mean I don't know but ..."
He tells us why he did it the way he did it.
