Lilly wasn't sure how it happened.
But a few days after Zach slapped her, Dean confronted Lilly.
She was sat in the common room while Zach was still eating in the Great Hall. She had a mirror and was inspecting the bruise on her eye. It was still a dark, murky purple but had started to go paler on the outside.
Despite it being days ago, Lilly still flinched every time she merely brushed over her eye.
Suddenly, Dean walked up to where Lilly was sat and plopped down on a chair just inches to the left from Lilly's.
"Are you okay?" He asked seriously, his deep voice gravely.
"Uh. Yeah. Why wouldn't I be?" She replied, tucking the mirror in her pocket.
"C'mon. It's me. You can talk to me." He smiled comfortingly and put his hand on Lilly's knee but moved it away as she flinched.
"I don't know what you're talking about. I'm fine." She couldn't look Dean in the eye as she said the lie.
"Lilly. Your eye. That's a really nasty bruise. How'd you get it?" He asked, no trace of a smile on his face now.
"It's nothing really. I just walked into my bed in the dark. It's nothing big." She had arranged this lie with Zach.
"Lilly. Is anything going on?"
"Going on? What do you mean 'Going on'?" She looked up at Dean and the worry etched into his smooth face.
"I mean. Are you sure someone hasn't done this to you?"
Lilly just stared. Unable to speak.
"I'm not accusing anyone but bruises like that don't just happen from walking into a bed. Something's happened and you know it has." Dean persisted.
Lilly blinked a few times and had to take a minute to get her head straight, even then she couldn't say anything so she just looked at her feet.
"Lilly?" Dean asked gently, placing his hand cautiously on Lilly's. She looked up slowly.
"Someone did this to you didn't they?" He asked quietly. Lilly looked behind her so see they were out of sight, hidden behind a few chairs.
She nodded once.
"Okay." He sighed, tightening his grip on her hand a little.
"Who did it to you?" He whispered.
A tear rolled silently down Lilly's cheek.
"It was Zach wasn't it?" He said slowly.
Lilly just nodded, she couldn't get any words out.
"How did you know?" She asked hoarsely when she found her voice.
"I kind of guessed. I mean. The way he was that night, he looked so angry."
Lilly laughed harshly.
"Angry. You could say that."
"What?" Dean questioned.
"He did it that night." She mumbled.
"Lilly! Why didn't you tell me?" He whispered, moving closer to her. She could see concern in his beautiful emerald eyes.
"Because." She didn't really have a reason but continued.
"Because I couldn't. I just couldn't Dean." She began to sob, quietly but loud enough for Dean to head the obvious sadness in her crying.
The next thing Lilly knew her lips were pressed gently against Dean's, her palm pressed on his cheek and his arm wrapped around her shoulders. Lilly was the first to pull away but instantly missed the feeling of Dean's lips.
Dean breathed out.
"You don't know how long I've wanted to do that Lilly."
"You know when something feels so right but shouldn't?" Lilly asked.
"Yeah?" Dean whispered, a ghost of a smirk on his face.
"That was what I just felt." She sighed but couldn't stop herself from grinning at him.
Dean laughed, short and breathless.
"Dean. You can't tell anyone about Zach. Okay?" Lilly said, suddenly serious.
"Okay. Don't worry, I wouldn't. You mean too much to me." He grinned at her and placed a light kiss on her cheek.
