Grady looked towards Lilly who still seemed rather cold despite having a sweater on, and after a moment of thought, he decided to take off his hoody, draping it around her carefully. "I-I'll try to get one started..." He said quietly, walking out the cave for a moment to gather a few sticks, dried bits of grass, and some rocks. Coming back inside, he assembled a small, rough, but workable firepit and took out his pocket-knife to carve a hole in the middle of the thickest stick before putting his pocket-knife away again, placing a sharper, smaller stick into the little indentation he'd made with the stick and started rubbing the stick with his hands, rotating it left and right quickly, trying to start a fire... It took a while, but smoke started to come from it as a small flame emerged from the stick, causing him to drop the stick he had been holding onto the firepit in surprise, though thankfully enough, they has a small, crude, campfire going now.
