I wish that video was as clear cut as you say, However if you view the interruption the preceded that interruption, she clearly and specifically tells No White Guilt that she will never forgive him for what he did to her. And to not believe him because he is a shape shifting ghost.
With all of that context, you now expect all of us to assume that she switches the person she is talking about to JF? She never specifies that she is talking about anyone else.
And you want us to assume that she is asking No White Guilt, the person that she will never forgive for what he did to her, for help?
Not to mention, Mama JF has had plenty of opportunities to upload her own videos later. And she never complained about JF trying to kill her. She had a cell phone. She never called the police? She never called her parents or sister to complain that JF was trying to kill her? If she had, I would have expected JF to be sitting in jail right now while the RCMP figure this out. The RMPC would have clear probable cause to enter his house and search it.
How do we know she had opportunity to upload her own videos? Maybe I've missed this, but did MamaJF have any sort of internet presence during her relationship with JF? Do we know for a fact she had unfettered access to a computer or a phone?
We know, per the neighbors, that MamaJF's parents didn't like JF and probably would have loved for her to leave him for good. But abusive relationships are more complicated and insidious than that. We've seen from other videos how devoted she was to him, how desperately she wanted his approval. She loved him. He probably had her convinced that she was just a dumb potato who couldn't do anything right. The term has been overused with such vigor by SJWs that just saying it will cause some eyes to roll, but JF is very much gAsLiGhTiNg in this video. Elora is mistaken, he says. She's confused, she's wrong, she's crazy.
The body language is also telling. JF is shaking nervously at the beginning. Elora seems to be making a concerted effort not to touch JF. As she leans in to the camera, she puts her arm around the back of the chair rather than JF's shoulder or back. Even when JF pushes her away, she doesn't touch him. Instead of trying to comfort her, he angrily lashes out at her, seems to be telling her to stop talking or else when the audio is off. He doesn't comfort his distraught wife or say "calm down, that's not the guy who hurt you." He just wants her to go away.
Elora's of diminished capacity, that's obvious. Maybe in her low IQ mind she thinks that accusing No White Guilt of the things JF has done will keep JF from retaliating against her after the stream ends. Maybe she thinks all of JF's little manosphere friends are complicit in a conspiracy to hurt her and her statement is intended for the audience rather than No White Guilt specifically. Either way, JF's convoluted and overlong story to me reeks of ass-covering rather than a rational explanation for her behavior.
Regarding why he hasn't been arrested yet, it's probably because RCMP is watching him and knows he isn't a flight risk (no money, nowhere to go) and is letting him continue to tie his own noose via his statements on his streams. He seems confident that he's not a suspect so they're probably waiting for him to get (even more) sloppy. Elora isn't with her family, has no money or means or transport, hasn't been spotted, and it's winter; it's virtually a guarantee that she's dead.
He didn't kill her the first time she left him. All he did was make it explicitly clear that she was going to be replaced and he would be done with her. And he gave her a.... deadline.
So what about her leaving him this time would have warranted death?
He would not be the first spousal murderer who didn't do it intentionally. Maybe he was just knocking her around like he had done before, she hit her head, lights out.
