Now that I know this I love the idea of each season being set in drastically different time periods.

I thought the purpose of Billy being there was to set the record straight and provide some kind of clarity on what happened from the higher ups. But Billy being Billy didn't do any of that, giving obviously false answers or refusing to answer certain questions. If his goal was to clear his name, he failed miserably and this played out in the producers favour.

Honestly I thought that one was a little better.

I would love a Bond movie set in the 60's given what we know and what transpired. They could have some real fun.
