I'm pretty sure the only one who knows that is Burnie. But I would guess it's because of either their actor's unavailability for recording, some plot-related thingamajig, or just because they just prefer to be gay and/or a pacifier in peace, away from Sarge's homophobic, warlike, grif-hating ranting.

To be fair, that's an understandable motive.
