Slaughterhouse 5 sheds some (violet) light on Tyrell’s death

Hmm, the unstuck in time part is interesting since Fyrell does seem somewhat aware. That's interesting. Thanks.

Dammm... all these conspiracy theories for a Kurt Vonnagut reference?

Good catch! Tyrell has lost everyone he loved. Even Elliot to a degree once realizing Elliot never really cared about him.

Not sure if this was intentional or not. Here's what Wallstrom had to say about the scene:

"It wasn't clear to me what that was. Sam and I talked about it, but in my mind, we weren't sure if it's something that only we see, or if it's something that's in his head. When I thought about it, it was so much about coming to peace with everything finally working out. For me, I saw it as him realizing that his son would be okay. It's not the way he planned things, but his son will be okay now, and Elliot will be okay, too — and he'll take down Whiterose. It's a relief for Tyrell. I think he's thinking: 'All of this struggle, it was useless, but it's fine now. I'm going to die now.'"

So if Sam intended the reference, he didn't want to share it with his actors during filming.
