Yep thats it, I don't see the body language, not saying its not there, I just don't see it. I just want to be clear I'm not defending him, just wanted to chime in some throughts I've had.
I can understand not noticing it, but honestly, the cues of their body language seem quite obvious to me on rewatching the specific clip of them talking about Ryan. Not sure what you're seeing, but this is what I noticed (and forgive the over-analysis):
- Firstly, the fact that Gavin and Jeremy are dead silent for the entire second half of the video. Geoff and Ray throw in little comments here and there, and I think Andy Blanchard speaks maybe once after the midpoint of the video, but most of the speaking is done by Michael.
- When Michael's talking about Ryan wanting to stay an extra day to "sleep in," Geoff looks off into the distance sort of absently, like he's thinking hard about something, and continues doing so even after he turns his head to look at Michael. Jeremy does the same thing, but he's biting his nails and his lip while staring hard at the table; all of those things are common tells of anxiety (not that he has anxiety, but that he may have been feeling anxious in the moment).
- When Ray says "that sounds like a cry for help from Ryan," he's sort of smiling at first, but the smile drops pretty quickly after he says it.
- Michael seems to realize that he fucked up mid-sentence (particularly after he says that Ryan wants to avoid going back to "that nightmare," i.e. his family) and tries to cover it up by saying that Ryan clearly loves his kids because they show up in his streams so much. Ray responds pretty quickly that showing the kids off in streams is "easy money," and he's making a weird face that's definitely not a smile at that point.
- And, of course, that painfully awkward silence at the end. Geoff lets out a giant sigh (which does sound troubled, honestly), Jeremy takes a huge swig of his drink, Ray is staring at Michael and shaking his head repeatedly, and everyone else just looks really uncomfortable. Michael's comment that they "didn't 'Jack' Ryan" seems to be an indicator to change the subject, and they almost immediately do so; Fiona just so happens to show up with a puppy immediately after Michael says this, which seems... weirdly convenient.
This is all complete conjecture, of course, but there is a clear air of discomfort in this little moment right before Fiona brings in the puppy. I can't specify why, exactly, but it's pretty clear that at least a few of them realized that something was up during this conversation.
