Yeah... I did a bit of experimenting a while back. I had a high-heart Liberal convert to Conservative, get kidnapped and returned to the base. They were fairly easy to re-educate, but I can't remember if it took less than three days. What I can remember was that they could escape right away, because they had enough "days in captivity" for that.
'Twas fun, I must try that again... for others wishing to do that, just one word: GAVEL.
Relates question, using the conservativeifying method and kidnapping ex-squad members, can you make them sleepers?
ONLY if they're enlightened before the cons find out.
And that's going to be hard, because the Liberals typically have been "missing" for months if not years...
But! Another seldom seen rule quip kicks in to make this possible. So rare I've never seen it in action apart from testing it once. For kidnapped people with fairly high heart and at least some wisdom, there's a 1/4 chance of the conversion being so convincing the cops won't consider it a kidnapping anymore, meaning they can resume their jobs as if the kidnapping wasn't reported in the first place. Conservafied Liberals qualify easily for this.
So if my Liberal right hand man gets conservied, and I kidnap them and enlighten them, they'll be unfit as sleepers because they were already reported as active members before? I didn't think the reported missing thing was kept track of past the enlightening.
Also, the bonus conversion with high heart and low wisdom only takes away the "wanted for rehab" thing, because the members announce their entry into the squad was by choice publicly. It doesn't let them become sleepers IIRC.
