Jack gives a broad, cheeky grin, with a twinkle in his eye as he whispers, "Ah well, you know, I have a couple of tricks up my sleeves. Could try to put the little tyke to sleep for a bit, give our halfling friend a chance to sneak away. Or light up mommy yeti with a bit of ye' olde fairy dust and make her more luminous than a moonbeam on fresh snow." The corner of Jack's mouth twists into a sly smirk, "And that could offer us a blizzard's edge in this chilly confrontation."
"Or, if we have the time..." Jack strokes his goatee and thinks a bit, "well, we would, wouldn't we, if it were naptime? I could try my hand at diplomacy, though I don't speak yeti, and that big one probably prefers skull-breakers over ice-breakers."
"Or I could summon a frost flower as a peace offering. It's said that yetis appreciate the rare beauty of such a flower, right? A sign of good faith and all that."
