Now that the full Reality Fracture story is out, I'm still left with some lingering questions about the mechanics of the Echoverse.

For starters, why do the echoes of Ajani, Garruk, Liliana, and Chandra obey Jace? We don't get a ton of dialogue from most of them but I didn't get the impression that he was mind-controlling them, so what are their motivations? The Legends of Reality Fracture page has one line for each blurb about why their roles in this new reality, but Garruk's and Ajani's are just about how they're Jace's enforcers.

Do they worship The Theorist as a god and therefore unquestioningly carry out his will? Is it a question of self-preservation — either I steal my doppelgänger's soul or I won't be real? For that matter, why do they seem to have full personalities while the story makes a point of Tam's classmates being automatons without souls?

If self-preservation is their motivation, why do they not planeswalk away upon Jace's death? Instead, they fade from existence, but Emrakul hadn't even finished eating the plane at that point, so does that mean they're more directly linked to Jace?

I'm kinda lost here (and a little disappointed that lingering Echoverse planeswalkers won't be a plot thread going forward), so if anyone can help clarify I'd appreciate it.

I looked this up and found a 10-year-old post on the subject but was wondering if anyone could shed a little more light on the difference between these two terms, which seem very similar.

Is "ipso facto" more a way of saying "therefore" while "per se" corresponds more to "intrinsically"? Thanks for any help you can provide!
