[@Pathfinder]Yeah I saw that, and had a few questions on that. Like Halting asked, are these Developed Gems or are they still needing to be born? and if that latter, isn't that more harmful to the Gem then helpful? Like, taking them out before their ready would likely cause deformations and defects within them that could be avoided. Not to mention that I don't quite know what Eise thought they'd do with them afterwards. Sending them to the Rebellion makes them no different then Homeworld, but keeping them seems to speak of an excessive lack of forethought on their part, especially if they took them out while they're still under-developed, which again, I don't think would be very wise(and also excessively hard to hide), while hiding developed Gems seems borderline impossible, impractical, and a likely way to get shattered for Treason very quickly since those Gems will likely want answers, explanations, and not like staying put. 

Edit: Telling them not to take part in the war would also be rather weak argument since, as we've been told in the show, Gems are born knowing what they're made for and probably the gist of how to accomplish it at least. As such, warrior gems would likely go out to the front lines anyway and point the finger directly at Eise as they do it for treason.
