No, he didn't. And Stanley was already gone by then.
Charlie can't have any veiled Archons within 6 hexes of any GK city without paying huge fines automagically. We wasn't paying those fines, so they must not be any Archons near Spacerock. I already said that Charlie would have surveillance of Parson in the MK, but that would make it less likely that Charlie would notice Stanley when he flew away from Spacerock, not more likely.
Not that it matters, but Parson would have had no reason to enter the tunnel. The portal for GK (the city) doesn't work anymore because it's not a capital. GK (the side) has only one portal; it takes people to and from Spacerock.
