Draco wasn't sure what to expect from Astoria's surprise, but at the very least anything she could have thought of would be distraction from his other thoughts.
He could care less about who had knocked up Professor Tonks, or jilted her. He could care less about the five hour Quidditch match that was still being talked about in the common room. He was too busy waiting for Death Eaters to descend on the school like a scourge to really worry overmuch about anything. Waiting for his arm to burn, and to have to take up his role as Snape's spy, whatever that entailed.
Time with Astoria seemed like freedom, at least for a few hours.
He was impeccably dressed when he met her, black slacks and a turtleneck and warm sweater under his robes. She looked casual, and even approaching from behind he had no doubt it was her. He caught one end of her scarf as it flew in the winter air behind her, smiling, tucking it back around her throat as he came to face her.
