Neville tilted his head, trying to remember if he was supposed to know who she was. Was she someone that he'd met in the future? Someone who'd impacted their future? But for the life of him, Neville just didn't know who she was.
Smiling at her - she couldn't be too bad if he'd never heard of her - Neville nodded. "It's a pleasure to meet you Miss Duncannon." He understood why she was going to leave. After all, he couldn't blame her. But at the same time, the thought of being alone with Snape - Severus - made him even more nervous.
Turning back to Severus, he shook his hand. "Indeed. It's a...pleasure to meet you too." It kind of was nice to meet him. It was weird to see him in the light of someone other than a teacher. He wasn't used to it - he'd always been scared of this man. But now? He was actually younger than Neville.
Nodding, he walked into the classroom and leaned against the door, trying to calm himself down so he wouldn't embarass himself too much.
