Quote from Joao Wockeez »Is there any chance Jace is under Bolas control? i mean it isnt that far fetched to assume Lord Nicolas may have put a trigger in Jace's head that would turn Jace into one of his minions, idk about you guys, but i doubt the fact that Jace ended up in Ixalan is just a coincidence.
It's been posited before, but I don't think that's the case. Vraska specifically calls out that the spell Bolas gave her to contact his agent crosses between planes, and that she didn't even know it was possible for a spell to do that. As that's the case, there would be no reason to send his Agent to Ixalan until Vraska locates the object, that just leaves hiom with TWO trapped minions.
Now, he DID give her the spell before the confrontation with the Gatewatch, but it's also made clear that when Bolas faced off the with GW that straight up murdering them WAS an option. You wouldn't generally murder an agent in the middle of a mission. Beyond that, Jace simply doesn't possess a means of moving plane-bound items off world.
