She's in shock. She knows she is. She can't stop shaking and she feels sick.

Den watches Kit as she sits on the sofa in his flat. Dan and Rosa are talking to the police, so Dennis and his mum have agreed to watch the kids, and that means watching Kit too. He felt sick when he realised she was in the flat. Gog had assured him that it was all empty and that the family had gone away, that all he wanted to do was scare Kit. He needed a lookout, he'd said, and Dennis was perfect for the job.

He didn't smell the smoke until it was too late. Kit had been lucky at the time … she'd been downstairs with her parents, saying goodnight to them and her younger siblings. They only had a three bedroomed flat, so she shared with the baby. If she hadn't, no one would have gotten hurt.

Kelly heads over to Kit and puts an arm around her. "Do you want anything, love? Cuppa tea? Water?"

Kit shakes her head robotically. "No … I'm fine."

"No, you're not," Dennis tells her.

Kelly shoots him a glare. "Dennis –"

He ignores her and takes Kit's hand, pulling her up off the sofa and into his room, closing the door behind him. She stares at him. "What d'you think you're playing at?" she asks him. "I need to go back out there, the kids need me."

She moves to the door, but he blocks her, leaning against it. She knows it's a losing battle, really. He's bigger than her, after all.

"You're not okay," he says.

"I am, the paramedics said I'm fine. I didn't inhale that much smoke –"

"That is bullshit and you know it!" There's a moment of silence before he sighs, "Your little sister died. I know you must feel like hell right now."

She shakes her head. "No, Den, you don't know. You've got no fucking clue! You don't have any idea how this feels, how I feel! So don't you dare act like you do."

"So tell me," he urges. "Tell me it feels."

Kit runs her hands through her hair. "I feel numb. I feel guilty. I feel like if I had been in there, she'd be alive and that firefighter would be okay. If I had been in the room, I could've gotten her out, and everything would be okay. But it's not. Nothing's okay, Den." Her voice cracks and she falls apart, dropping to her knees on the floor, her arms wrapped around her torso, letting out everything she's been feeling for the past couple of hours.

He kneels beside her and pulls her into his arms, kissing her on the head. "I know, babe. I'm here for you, okay? You're not alone."

She clutches at his hands, lacing their fingers together tightly. "I'm gonna kill him," she mumbles as the tears subside.

"What?"

"Gog. I know he did it, Den. I'm gonna kill him for it. Just you wait. He won't get away with this, not if I have anything to do with it."

"You can't think like that," he tells her fiercely.

She looks up at him and shrugs. "Why?" she demands. "What have I got to lose?"

"Nothing, I suppose. But I've got you to lose, and I can't have that. Just promise me you won't do anything drastic, all right? Promise me, Kit."

"Okay, Den."

He shakes his head. "No," he says, "you need to say it. Say that you promise, Kit, and I'll hold you to it."

She's silent for a few moments, and then she nods. "I promise, Den. I won't do anything drastic … I'll just think about it. I'll tell the police it was him, I'll get him put away for life. It's what he deserves. He deserves to be locked up and never let out, so he can't hurt anyone."

"I know he does. Don't worry, they'll get him. You won't ever have to see him again."

He doesn't speak the next words, but he thinks them loudly enough that he wishes she could hear them. "That's my promise."
