Neville had closed the journal, and stepping towards his own fireplace, thrown in the green powder and spoke clearly.
"Hogwart's Headmaster's office."
He'd stepped in,and in what felt like only moments, stepped out to find himself in the office. Severus Snape sat at his desk, and Neville raised his wand and quickly cast a cleansing spell so as not to leave ash on the man's floor.
"Severus," he said as he moved to step forward, "I mean, Sir. You requested I come?" he asked, trying not to let his voice show his nervousness. Neville took a quick breath and let his shoulders roll back slightly and drop, raising him up to his full height and giving him more confidence. His eyes lifted to meet Severus's, and he felt an inner calm come over him, sort of like looking into the mouth of a storm.
"You wanted to meet with me and I am happy to oblige you," he added. There were questions he wanted to ask but he made himself wait, to be silent so he could hear Snape's reason for the quick meeting.
