I'm fine with being removed from SAINT, so long as I can get him back in without having to get permission from anyone but the GM (Navian) to do so.
Someone alerted me to this whole little thing. Here's the actual answer: A SAINT operative assigned under a captain's command can be demoted by that captain in the field and suspended from performing their duties as an operative. The operative can even be made to carry out another job under their current chain of command. But they would remain in their actual occupation (03 Intelligence Operative) until relieved of such by the Executive Intelligence Directorate and Star Army Personnel Command.I don't run SAINT, so as long as Fyodor is still FM-approved (and I don't see why he wouldn't be) he'd be able to get back in offscreen automatically after the mission
There's no such thing as "getting out of SAINT for messing up and then being made an operative again later." If the character did something egregious enough to lose their SAINT status, it would be permanent—which is a decision the GM can make—but from what I can gather that didn't happen so no worries, really.
tl;dr: Star Army Intelligence doesn't abide f-ups, so don't throw around getting kicked out of SAINT as punishment unless you accept the gravity of the act and its permanency.
Just a quick note because y'all seemed confused.
