Kurt visibly tensed at Emma's words, the topic completely catching him off guard. "My parents?" he blinked, immediately wondering what had brought this on. He had really never spoken about his family life to anyone around the school though most of the staff and his friends knew that he had been adopted. In all honesty it wasn't a subject he thought about very often anymore unless it was Parent's Day at the school or something and after an entire childhood of wondering he had mostly come to terms with the fact that his biological parents were either dead or would simply remain unknown to him forever.
"I-er. Nothing, really," he replied, shaking his head. "I only know that my mother had abandoned me and then my adoptive mother found me. She always told me that she did not know anything about my parents," he explained though he was fairly sure Ms. Frost already knew as much from his file. "Why do you ask?" he ventured to ask, peering up at her.
