So here's something I just discovered (probably missed everyone else discovering it months ago, but anyway):
If you chose to show the Jade video to the DIKs, and ultimately the video gets into Burke's hands, the mc gets this look from Burke when you go to his house (he doesn't look at the mc like this if he never saw the Jade sex video):
Up until right now, I wasn't 100% sure that Burke knew it was the mc in that video, since when we see Burke watching it, we can't see the mc's face, so I thought Burke maybe couldn't see his face either. But this scene cements it, Burke knows it was the mc fucking his wife!
I can't read his look thought, it's not like he's seething with hatred.
