^ Prime Landry? She's Ripper-bait. I think you mean MU Landry...
And MU Stamets was vaporized by phaser fire. No chance for him to be spore-resurrected...
Prime Landry *and* Mirror Landry. Like Culber (whose neck was broken), they all died "natural" deaths (Ripperfied and explosified). The only thing all the characters I mentioned share is that their often violent deaths occurred somewhere near the spore drive, and match the pattern laid by Culber who later appeared to show up in the Mushroom Purgatory.
I mean, I don't think that was Culber (it was a hallucination *or maybe* the Mycelium becoming sentient). But if it was Culber, I don't see what separates his death from the other nearby violent deaths I've mentioned.
