"Mulder?" Scully practically whispered, "What are you doing here?"

"I don't think that's the most important question right now, do you?" he replied, glaring harshly at her, " I was planning to surprise you this morning." He looked around at Mike; "I see it's me who's getting the surprise."

"This isn't what it looks like," she began but he cut her off,

"It better not be because I can tell you exactly what it looks like from where I'm standing," he almost shouted. He was about to continue when a high pitched shriek emanated from behind Scully and a toddler ran out of her bedroom holding a cuddly blue rabbit and giggling madly.

"Dadadadada!" the child squealed as he spotted Mike, running toward him and flinging into his legs with enough force to knock him back several steps. The child caught sight of Mulder and shot him a brief suspicious glance before turning back to his father. Mulder turned back to Scully and stared at her;

"Explain. Now." he said levelly.

"Can we talk in my bedroom?" She asked quietly, indicating the toddler who was now bouncing the rabbit against his dad's thigh. Mulder nodded.

"Should we leave Dana?" the man asked as she turned towards her room. Mulder felt the rage and jealousy he was trying to keep under control bubble up again; who the hell was this guy to think he could call her Dana in front of him? Impertinent bastard. He heard Scully telling Mike not to leave, that she would get everything smoothed out and telling him where to find some porridge oats for the little boy whose name was revealed to be Joel. She led Mulder to her bedroom and sat on the edge of the bed looking at him as he closed the door. He simply stared at her, trying to see through her, into her mind.

"Mulder, Mike is…" she started but Mulder cut her off again.

"Have you slept with him?"

"What?"

"You heard me, have you slept with him?" Mulder repeated, louder than before.

"No, I…" she started but Mulder could see from her face that she was lying; she couldn't keep a secret from him to save her life.

"Liar!" he shouted at her, refusing to let the tears he wanted to shed come as he saw them well up in her eyes. "Tell me the truth Scully!"

"I didn't sleep with him last night!" she shouted back at him, "I would never betray you like that."

"Like that?" he asked, repeating her tone back at her, "how would you betray me exactly then?"

"I didn't mean it like that!" she managed to utter between sobs as the tears began streaming down her cheeks.

"Don't give me this shit," Mulder spat at her. "So if you didn't sleep with him last night, when was it Scully? Last weekend when you said you were meeting Kathy at the cinema? When?" Scully looked up at him and took a deep breath.

"It was sixteen years ago" she said quietly. Mulder simply stared; of all the answers he had been expecting, that was not one of them.
