"We could do this at mine you know?" She told him, trying not to scold, "there would be more room."

They were both squeezed into Sherlock's tiny Uni room, Lucille sat on the three quarter size bed, her knees drawn up to her chin while Sherlock paced the floor scribbling notes and pinning them to the wall as thoughts occurred to him.

"She lived in Dorms didn't she?" he muttered "I need to be as close, your house, it's not close, it's not the same."

She looked at her watch, it was nearly 10pm they'd missed dinner, not that he would eat, but she' been here most of the day. "Sherlock it's late, do you want…"

"Worried about your reputation , Lu?" he interrupted and when she scoffed he grinned. "I think most of the college thinks we're shagging anyway."

"I was more concerned your conquest from last night might return." She teased, too late she saw the crimson flush run below his bruised chin, "Oh Sherlock, I'm sorry."

"It's nothing" he snapped, stepping back and studying his wall.

"Sherlock, you must stop punishing yourself, you've got to stop doing this."

He spun around to face her "What the hell would you know about it? You've never let anyone touch you, how dare you judge me, how dare you judge anyone?"

"I'm worried about you, I'm not judging you, I just don't want to see you get hurt."

"Oh!" Sherlock stopped scowling, his vision cleared, and his head snapped back towards his wall, "tell me about the father."
