Geralt is less upset. He's tipsy, actually, and he finds a beer someone set on a table and has remained, miraculously, upright. He holds it in his left hand and boots the closest chipmunk in the face before stabbing the meat carving knife into the thing's skull. He pauses and hops a few steps backwards so he has time to chug down half the beer, because the world has gone mad, and another beer won't matter either way. He may as well have fun with this, because there's either an end to the chipmunks or there isn't, and he'd rather go drunk because why the fuck not, death is coming and maybe via chipmunks.He looks at Ben and flashes the werewolf a sozzled grin.

"You're nippier than you look. Lily! Watch my back and I'll take yours!" he calls, and does her the battlefield honour of turning his back on her. It's how soldiers say 'we're friends'. In fact, he tests it by letting a chipmunk run at him from behind. Will she bother? Or is she only concerned with herself? Maybe Geralt's testing for humanity and if he needs to slay a monster, even now.
