I think you missed a part (that others seemed to have missed as well)
When Kirsten goes to Tyler’s compound, he tells her that after she stabbed him, he wasn’t able to wrangle the kids very well so they started to try to implement the prophecy themselves- the kids who had the mines at the golf resort were rogue
— now we don’t have to assume Tyler is a reliable narrator - but we don’t have to doubt it either
The thing that works about believing Tyler’s story is that it makes Kirsten’s stabbing of him the indirect cause of both the club house deaths and probably Sarah’s
All bc she was trying to protect everyone
And I’m not trying to be snarky but I’m not sure you ever believed this show when it told you that it wasn’t like all the other apocalypse shows
And I’m not removing myself from that either- when Alex gave Tyler the knife for Hamlet, I had the rest of the show mapped in my head involving stabbing Clark and the Jeevan was going to echo his ep 1 walk to stage but this time he could save the actor, et al
But luckily the writers are better than I am and wrote something much more subtle and beautiful
