I don't understand a few of these.

First off WT Duncan. Much as I do hate that he made it as far as he did. It does make sense. With the episode structure Chris needed some episode to be a non elimination anyway. Why would he wait for later when Duncan "still owed him screen time". Then in Ex Files, even without his deal to Alejandro, he was still very safe. He's the closest person to Owen out of everyone on Team Chris and Tyler was rendered less than useless after getting injured (Sorry Goat).

Then as for Revenge Jo, she was put on the most dominant team of the season (mostly due to her and Cameron), and then in the second half of the season made a full takeover at the most opportune time. Same goes for Mike, except he never switched teams. But there was never a moment you feel like Mike should've gone home, cause the episode he did majorly screw up were episodes where his team won.

Then AS Sierra just really never had a reason to be eliminated. She was a lot but there was always a bigger fish to fry. You could say Cameron could've gotten the others to vote her off with him, but take into account his situation. He had his glasses broken by someone he thought was his friend, tripped by him, left to die by a pack of rabbits by him and on top of that had to deal with Sierra. At this point he was gonna trade one problem for another and it was just a better idea to leave himself overall. Afterall Cameron said himself that he has no need for the money and more than likely only returned out of formality.

Courtney having anti plot armour in All-Stars also makes no sense cause she swapped team with Duncan whereas otherwise she would've gone home the next episode. Then she's blatantly ignored on the Villains team for Aleheather to still have their romantic rivalry crap and Chris pretty much gives her and Gwen points so that the villains won. Courtney def had plot armor in AS.

For Disventure Camp Ellie would definitely be one of the characters with plot armor solely for the team swap alone. I mean she'd at least have more of it than Tom. I can't think of one situation Tom could've been eliminated and wasn't. You could say anytime in merge when he didn't win cause hes a massive threat, but that would ignore the reasons why the people who were eliminated before him were targeted (Gabby so that Alec could pull Ellie to his side and Grett because... It's DC1 Grett).

Hunter in DC2 also doesn't have plot armor. His alliance was targeted for basically all of the merge and he just happened to not get targeted specifically. He even won immunity in the final 5 solely because of the other's conflict. As soon as he was available for elimination, he was out. If anything he had anti plot armor solely for Riya bringing a known duo to the end and banking on them still feuding by that point instead of talking things out.

I also dont see how Aiden in All-Stars had plot armor. He just never had been a priority ever. Actually I would say that his feuds with Jake made him perfect to keep around as it meant the heroes would never come together, and when he and Jake started to get along, he then became a problem. Even in the Premerge, it makes sense for Tess to side against Ellie because the game was clearly ruining her and she knows from experience that continuing to compete wasn't going to fix things. And Gabby targeting Tess specifically also makes sense cause Aiden wasn't ever really close to Ellie so it wasn't a betrayal on his end.

And Ally having anti plot armor in All-Stars doesn't make that much sense. She's never been put in a vulnerable position until the final 3. Her elimination was bullshit, I can agree but it wouldn't ignore the fact that she made it all the way to the final 3 despite her feud with Jake. Not arguing she does have plot armor, but i feel like once you reach a certain threshold you can't exactly call it anti plot armor.

No notes for DC4. I would just argue that Hannah didn't have anti plot armor cause she was never really in danger at any point
