I don't think the Archons are lying. First of all, the High Elves weren't specifically looking for her until she killed them. They were, in fact, resting and eating. She attacked them unprovoked. The fact that a group charged in to see why their natural allies were attacked isn't exactly an unreasonable response no matter who the attacker is. Second, her attacks on those scouts have been preemptive. Third, we have seen no signs of pursuit at all.
We are looking at this through the lens of an escaped prisoner, and one with a very high regard for her worth. Any fugitive has to assume that they are being tracked. It's the only way to stay alive. If you assume that you aren't being pursued and act on that, if you're wrong you are very quickly a prisoner again. Our narrator has everything she sees colored by that, admittedly, not unreasonable presupposition. Given that Jillian is something of a narcissist anyway, the idea that there might not
be a pursuit has never crossed her mind. Since only have her point of view
, pursuit has been assumed.
I had my doubts about whether or not her escape was engineered or honest when this started. It wasn't unreasonable to assume that Wanda let her go intentionally, but I don't think that's the case. In this comic
, Jillian asks Wanda to trust her and Wanda says that she made that mistake before. I've always kind of wondered what she meant by that. She could be talking about the Suggestion spell, but that doesn't sit right with me. Jillian was able to break out because Wanda gave her leeway to leave the coffin for a bit. That enabled her to get the ceramic cup which let her break the coffin. All of this is a direct result of her being let out. Wanda trusted her, even just a little bit, and Jillian used it to escape.
Since then, Jillian might have simply been too much trouble to worry about taking back. The risk/reward analysis wasn't in the favor of recovery, so Olive decided to just let her run. Might be a lesson to Wanda as well. "Let your toys go and you don't get them back."
Just a theory.
