"Caroline Todd, Will you marry me?"

"Yes, of course I will, yes!"

"Mac. You know when you asked me to marry you?"

"Mmm."

"You know I was going to say something."
"Mmm."

"I really need to tell you now. I've left it for far too long and I should have told you then."

"What is it?" Mac asked, turning from the television.

Caroline paced nervously along the length of the room. Mac got up, placing his hands on Caroline's shoulders.

"Calm down. Tell me what's wrong." Mac pulled her closer, his hands sliding down her arms to take hold of her hands. Caroline trembled all over; her knee's going weak, dreading his reaction.

"Mac… I'm pregnant."

Caroline wandered down the corridors, searching for Guy. She ran different theories through her head, different ways to tell him about her engagement. She didn't want to tell him about the baby yet, Mac didn't even know. She caught sight of Guy, jogging quickly after him.

"Guy!" She shouted, drawing his attention to her.

"Ah, the lovely Caroline. How can I help you?" Guy asked cheerily.

"Yeah, um, Guy. Listen. I have something to tell you."

"Go on."

"Mac asked me to marry him." Guy stayed silent, a glint of sadness in his eyes..

"What did you say?" He asked quietly.

"I said yes." Caroline told him, crossing her arms.

"Congratulations. I'm happy for you."

"I'll be moving in with him soon so you'll have the house to yourself."

"Great. Thanks." Guy grumbled, walking off down the corridor obviously looking for somewhere to sulk.

"Well that went well." Caroline said to herself, sighing quietly as she wandered back to theatre for yet another operation.

Mac's face lit up like a kid on christmas morning.

"That's fantastic!"

Caroline shook her head. "There is something else though."

Mac frowned, confused. "What else?"

She took a deep breath, shaking, "I think it could be Guys."

Mac's face dropped is shock. "W..What? How? When?"

Caroline started to explain. "I'm sorry Mac, I never meant for this to happen. It was when Holly had come round to your place to explain about Mackenzie. When I got home I started playing poker with Guy; I had lost most of my money, so Guy bet me a kiss. I was upset and lonely and I didn't know what to do with myself. The kiss just turned into something more. I hadn't noticed till last week, what with all the shit between us and how busy the hospital was, I just didn't connect up the signs. I'm sorry Mac, I'm so, so sorry."

Mac backed off, not saying a word. He turned from her, grabbing his jacket, storming out of the flat, overwhelmed with fury, too angry to be his normal caring calm self.

Caroline watched him go, fighting the tears for as long as she could. It wasn't long before she collapsed onto the sofa, her tears soaking the pillow.

Mac sat at the bar, surrounded by empty glasses. He ordered another pint of Guinness, downing half of it as soon as the barmaid handed it to him. Head in his hands he tried to make sense of the last few hours. Guys. Guys' child. What did he do to deserve this? Everything that had ever gone wrong in his relationship with Caroline was usually to do with Guy. Holly being the one exception. Ugh, Holly. Why did he have to fall for her little sick plan? Why did everyone he love have to hurt him? He had to sort this.

Mac slammed his fist against the door of the house, struggling to keep his anger at bay. After a few move smacks, the door opened, revealing a tired looking Guy, still in his work clothes.

"What do you want?" He muttered, half asleep.

"You are the father of my fiancés child."

"Eh? What are you on about you scrawny poof?"

"You're a wanker." Mac snarled, lashing out, his fist making solid contact with Guys jaw, sending him flying back into the house. Mac leapt in after him, kicking Guy with all his strength.

"Jesus Mac! Calm Down!" Guy shouted, struggling to get to his feet.

"Calm down? Don't you tell me to fucking calm down!" Mac threw another punch at Guys face, his attempts getting weaker and weaker. Guy managed to clip Mac's face; fighting back, Mac aimed a last jab at Guys ribs before sinking to the floor.

"Why does it always happen to me?"

"I don't know but you really need to control your anger." Guy advised, pulling himself up to sit next to Mac. "Go home. You're completely pissed. You need to talk about this with Caroline; no doubt she's just as upset as you."

"Are you okay?" Mac asked, slurring his words.

"No, I think you've just broken my nose. I'll be fine. Are you okay?"
"Do I look okay?"
"No but I felt I should ask." Guy paused, looking at his drunken friend for a second. "I've never seen you like this before Mac. Do you want to talk about it?"

"No." Mac grumbled, picking himself up off the floor, "Sorry." Mac told Guy, closing the door behind him, leaving Guy alone in the house

"Fuck." Guy whispered, Mac's words sinking in. He was going to be a father. He was the father of Caroline's child.
