Harry left Pansy's about nine pm. He had let Hilly tell Pansy he would be gone overnight on Order business. His nerves were strained and he thought he might snap at her, or tell her the truth if she badgered. He didn't really want to do either so he had Hilly pass the message. The elf had been pleased to and had handed him some biscuits on the way out.
Once he reached the gates Harry slipped on his invisibilty cloak and walked through the halls to Severus's rooms. Slipping it off as he knocked on the door Harry waited for Severus to answer it. Thankful that at least this time he hadn't needed a glamour to hdie his appearance. He looked tired, but not as haggard as last time.
