Geralt steps over to take Waver, knowing the way out from here and clearly being able to tell that he needs help, and fast. Beside them, the witch says: "You lot are going to get the whole city burned down for good or ill, aren't you? Come on."

She straightens up and turns around, shoulders set. Deep breath, and then she launches into a charade at the incoming guards, begging for help for return of her wayward monsters. Geralt swears under his breath but can't stop her. He looks at Berserker.

"That ruse isn't gonna last. She can't get killed, alright?"

Imagine if a Dorcharcht witch ended up dead in the crossfire of Aefenglom rebels screwing around with normal city proceedings. It wouldn't matter that she's a Resistance agent, they'd all get crucified. He lets Waver claw him if he wants, and barks at the nearest newly-freed and terrified monster - feeling bad about leaning on the compulsion spell, but not having any other way to get them to hustle.

If they can just get out before anyone attempts to detain one of them, maybe they'll squeak by. The enforcer is dumbly trying to help their witch round up monsters, clearly not sure she's legit, but not being in the habit of questioning a mage.
