Colin hadn't been expecting the door to open when it did, so he fell in, letting out a small squeak. Zach's arms around him made him smile a little and he nuzzled against him. Zach was warm. He was cold. "I-I f-f-f-for-got to c-cast a charm." He leaned into him, shivering a little. "Sh-should get c-coat off. Mmm. Warm." He moved to take off his jacket, fingers fumbling with the buttons.
"C-can you h-help?" He laughed a little. At least it was warm in here. He was starting to warm up a little bit. He didn't really feel like doing much else but standing there and stealing Zach's body heat. Body heat was the good way to warm up. Someone had told him that once. Who was that again? He didn't remember at all. He just wished he could stop shivering so much. His muscles felt like they were having spasms. It was a bit uncomfortable.
