I also don't want to deprive anyone of joining in, but the only reason the gang's there is because of a confidential mission from the Frat. That's why Gert's asked Rolande to also stay out if possible.
Gert also has no intention of giving veiled hints to a man who's known to play the fool when it suits him. He'd be privately laughing his head off at our attempts at secret codes, while pretending not to have a clue at what we're trying to so. I know that I would.
Rolande may not be remaining upstairs (depending on his own inclination or Chicken Bone's). If not, he could talk to the bodyguards, who could quiz him about what the locals
do know about the weird group at the Maison. Even if he isn't, I'm sure Gerard wouldn't be averse to a bit of gossip on that point.
And let's face it, Brother Perrison's little omen is still hanging over our heads, so who knows what else might arise.
His only real danger is if stupidity is contagious and lethal. In which case, we’re all dead…-Gertrude
