This is where I wholeheartedly disagree with you. That dead end that got interrupted by the 7th showed that the MC wasn't about to survive what was about to happen. I don't see how anyone can read that dialogue there and think he was about to come out alive. Especially when she straight up told the MC "she wanted to play with him a bit more" or that her telling him everything"wouldn't change his fate". That's not something you say to someone when you're taking them to an Apostle against their will.
No matter what Ella says and how she acts, the choice of what's going to happen is up to the Apostle.
If the Apostle doesn't already know about the double trait and the connection to the Eye, she learns all about it during MC's second evolution where he gets connected to the Eye and while still connected with his ancestors he reads Klaus memories. Does the Apostle kill him or do anything bad to him after that? No, she even offers help. Does Ella and pretty much everyone in the game know the whereabouts of MC? Yes.
The Apostles serve the Eye faithfully and the Eye is willing to give MC power and wait for him to grow for whatever reason. So why would that encounter be deadly for MC just because Ella talked about a sealed fate? Perhaps it would be difficult or even dangerous, but outright fatal? Unlikely.
I'm also not exactly sure why you're so sure Ella won't kill the MC when she has and will let him die on several occasions, even while knowing he has both traits. Unlike with Deryl, she hasn't given SIN or her students a no kill rule for MC. Hex and Cole tries to kill the MC once and Hex succeeded in dumping him in a monster realm in the 2nd. Aglaecwif straight up kills you if you say no to breeding. We also can't forget Ella herself kills you personally for killing Christie. You might say she was pissed but that shouldn't matter since she's so intelligent and wants a person with both traits, right? This is after Jake's final fight by the way. She didn't care about no dual traits and devoured him with her tentacles.
All of those events happened while Ella knows you have both traits so it's odd that you feel like she wouldn't off the MC for Jake, who she knows she can control and manipulate. Hell, for all we know, she only wants one Arbiter awake and not more than one.
Because it requires a precedent for me to think that Ella is hostile to MC that it still hasn't happened. I don't think that Ella would prefer MC over Jake, because Jake is both easier to manipulate and has a seemingly stronger power, but
Jake has not yet demonstrated the double trait. So this comparison is completely pointless. If both had showcased the double trait, then I'd agree with you, althought at this point I doubt that Ella would even bother training MC at all.
Christie:
The better question is, If by the time Ella takes revenge for Christie, she knows about the double trait, then why doesn't she do anything similar to deadend3 regardless. Is it so hard for a level 5 to manhandle a level 2? There is also the training segment (the one with the earfuck), where she is shocked if you ask about her killing you.
As for why she kills you assuming that she know about the double trait? Because it's quite possible that MC's role is something that will allow Christie to thrive when things change. Without Christie, there is no point to any of it. Don't forget, MC's role is to make Ella's dreams come true (deadend2) and it's quite unlikely that her directive is aligned with her dreams because she is very dismissive, both as a young girl and during her fifth evolution.
Deadend3:
No matter what Ella says, if something is going to happen to MC, it will be the Apostle's decision. During the second evolution, if the Apostle didn't already know all about it, she sees that MC connects to the Eye and reads Klaus' memories while the post evolution connection is still active (the monster urges MC to devour Alice after MC reads Klaus memories). Does anything bad happen to MC since then? No. If anything, the monsters help MC.
Cole & Hex:
Jared outright says that Ella protects MC. The chances that Ella protects MC just from Jared are zero.
Cole has a lot of chances to kill MC but he doesn't take them. Cole knows of MC's powers and has seen him fight. Blowing up his head is hardly an intention to kill. Otherwise why would he go after the level 5 instead of just turning the level 2 into a boiled and bloody mess?
Hex only ever attacks MC once Ella is dead. First attack is when he dropped the dimension, second attack is during deadend39.
The only thing their behaviors prove is that they dislike MC. That has nothing to do with Ella and it's an indication that they don't recognize MC's role or why Ella wants to protect him.
Aglaecwif:
She is tasked with protecting the portal. MC has 2 options. Either kill her or accept the pact. The pact is given even if MC acts hateful towards monsters. If Aglaecwif killed him while he was trying to retreat, I'd agree with you. But killing him in self defense and while attempting to protect the portal isn't the same. Additionally Aglaecwif hates Ella.
You know what? I'll even level with you and say sure, she didn't kill the MC there in that dead end in her apartment. Sure, he somehow survived Ella's strike. That said, He definitely didn't survive beyond that scene and likely died when she got what she wanted. Which basically equals the same exact thing. MC was going to die no matter what. It doesn't matter if she didn't kill him there, he would've died later regardless because whatever she did was not good for the MC.
My idea about why MC doesn't survive regardless, has to do with the 7th, not the 4th. The 7th is after the 4th, Ella calls the 4th and 7th intercepts. I don't subscribe to the idea that whatever the MC would go through would kill him. It would be dangerous perhaps, but not outright fatal.
Seeing that scene for the first time without context makes it easy to think that MC is doomed no matter what. But we get A LOT of context after that, about MC's relationship with his monster parents. Unless we can prove that after the second evolution, something changed VERY drastically, then I just don't get why anyone would think that the Apostles are hostile to MC in any shape or form. Aside from the danger of monsterfication I don't see anything else here.
The only thing that makes sense to me is that the 4th would try to awaken MC's connection to the Eye, perhaps even force him to evolve which would be dangerous. But other than that? Absolutely nothing. The Eye would decide what is going to happen, and we have a fairly good grasp on how the Eye wants MC to progress.
Otherwise, after MC's second evolution where he finally shows his capabilities to the Apostles, he would be constantly on the run from them.
