House helplessly sat rubbing Chase's back as the younger man heaved over the toilet, spitting out the acidic bile which was now the only thing in his stomach. "You need to go to the hospital," House said once Chase had straightened up.

"It's just stomach flu."

"You haven't kept anything down for days – almost a week. Even if it is just stomach flu – which it isn't – you need to go to the hospital, or you're going to get really ill."

"I don't want to go," Chase said, sounding like a cranky teenager as he dragged himself over to the sink to clean his teeth.

"Tough." House stood up and went to stand behind the blonde, putting his arms around the skinny waist. "Please don't be a pain in the ass over this," he said softly. "I'm worried about you."

Chase leaned back slightly. "Fine, I'll go. But I still don't want to."

"Thank you." House pressed his lips against Chase's neck, kissing him softly. They both went back through to the bedroom that Chase had gone running out of and got dressed. Chase rubbed his hair dry with the towel that had been slung around his hips and combed it quickly, not feeling up to usual standards of grooming. "You really do feel like shit, don't you?" House observed. "You never leave your hair to dry on its own."

Chase shrugged and wormed his way into House's arms for a hug. "Too tired. And my head aches."

House frowned worriedly. "Let's go." As usual House drove like a maniac and they arrived at the hospital quickly. Wilson met them in House's office as the older man had requested. Chase sat down sleepily on the lounger and curled up in a ball as nausea threatened to hit him again. Wilson looked at House's worried face, silently asking what was wrong with the young man. "He's been throwing up for the past few days. Chase thinks it's stomach flu, I disagree. He hasn't kept anything down beside a bit of water."

"Has there been any blood in the vomit?"

"Not that I've seen," House replied, looking at his lover who appeared to have dozed off.

"Let's get some tests done." Wilson hesitantly put a hand on House's shoulder. "He'll be ok you know."

"Yeah." House attempted to smile at his friend before he moved to wake Chase. "Hey, wake up Princess."

"Don' call me that," the blonde mumbled, sitting up. He was pale and still felt queasy but was not in danger of throwing up for the time being.

"We need to run some tests. We'll take some blood, check for ulcers and maybe do a full body scan."

"You hate full body scans," Chase said, glaring slightly at House. He wasn't happy about being here even for a few blood tests let alone scans.

House shrugged. "I know. C'mon."

Chase stood up, grumbling the whole time and Wilson grabbed his arm when he saw the blonde stumble slightly. The Australian gave him a weak but grateful smile as they made their way to a room they could use to take blood and carry out tests and House handed Chase a hospital gown to change into. The smaller man didn't take it however, and took a step backwards, shaking his head. "No way."

House stepped forward to stand in front of him, wrapping an arm around him. "You'll need it for the scan," he said softly.

"If you do a scan, I'll put it on then. You don't need it for blood tests."

House lifted his hand to touch the blonde's face. "Ok." Chase sat on the edge of the bed while Wilson rummaged around in drawers, taking out syringes and various other things. House rolled the sleeves up on Chase's left arm and took a needle from his friend and quickly and expertly drew blood.

"I didn't know you could actually do this stuff," Chase said, with a feeble grin. "You always make me or one of the others do it." He winced as the needle went in and then again as House drew it out and covered the puncture with a small bandage.

Wilson snorted lightly at Chase's comment and House glared at both of them. "We should do an endoscopy and check for ulcers," House said, and the grin was instantly wiped off of Chase's face. "I'm sorry," House said quietly.

"I hate you both," Chase muttered as Wilson brought over the endoscope. House tossed Chase a lozenge to numb his throat while the two older doctors got the necessary equipment ready. The tiny camera was inserted into Chase's mouth and House told him to swallow as he gently guided it through his oesophagus until he reached the stomach. If the blonde had been able to talk he would have pointed out that he knew what to do – he'd carried out the procedure himself more times than he could count.

All three men watched the monitor – although Chase had to look away after a moment, feeling highly uncomfortable looking inside his own body – and looked closely for signs of any abnormalities. After what felt like an age to Chase House began to withdraw the endoscope. "No signs of ulcers or tumours," House said, relief showing in his voice, though he was still worried.

"Told you," Chase mumbled, his voice a little hoarse. Wilson handed him a cup of water and he sipped it gratefully.

House ignored him. "Let's do an ultrasound, see if that picks up on anything."

"Can't you go do the blood tests first," Chase moaned.

House threaded his fingers through Chase's hair. "We might as well do an ultrasound, it might save us some time."

"I think you're just enjoying torturing me," the Australian groused, his accent thick.

Wilson saw the pain in House's face which was quickly covered. "No. I'm really not. I'm fucking scared, Chase." The young man looked slightly ashamed, and both he and Wilson knew how much it took for House to admit he was scared.

"I know. I'm sorry. So am I." Chase reached out a hand to grab House's. "I love you."

"Love you too," he replied gruffly before taking the ultrasound wand that Wilson was holding out to him. "Ok, lay back, shirt up, hands above your head. Oh, and loosen your belt."

Chase couldn't help but feel a little turned on by House's orders as he did as he was told, pulling his shirt up and undoing his belt, pushing his jeans and boxers down slightly so his abdomen was fully exposed. House applied the cool lubricating jelly to the blonde's stomach, rubbing it around a little more than was necessary, and Chase blushed a deep red as he realised he was getting hard from this – they hadn't had sex for a while as Chase hadn't had the energy or felt much like it. He was mortified, knowing that his tight jeans would be doing nothing to hide the bulge from either House or Wilson.

"I really hate you," Chase hissed, and House simply smirked in response before putting the transducer to his abdomen. He moved it around for a while before he found anything, and all three men watched the screen as a small mass was shown. Chase swallowed. "A tumour?" he asked quietly, and House closed his eyes, frozen in place.

"Fuck!"

"House." Wilson reached out to touch his friend's arm. "Look."

The older man opened his eyes and looked back at the screen, glaring at the image. "What?" he asked roughly.

"This 'tumour' has a heartbeat."

Chase's head whipped to the side again to look at the screen. "What the fuck?"

House looked at his lover, open mouthed. "You're… pregnant."

"I'm… what?" Chase's voice was faint.

House sat down heavily, his hand dropping the transducer on the table. Wilson picked it up again, running it over Chase's abdomen till he once more found the darker mass. "It's definitely not a tumour. And it definitely has a heartbeat."

"Oh my God," Chase said weakly, before turning an accusing glare on House. "You knocked me up!" he shouted angrily before he grabbed a few tissues from a box, knocking Wilson's hand away and cleaning the gel from his stomach before standing up and doing his belt back up, and pulling his shirt down. Before either of the other men could react he was out of the door and on his way down the corridor.

House stood up to go after him, but Wilson grabbed his wrist. "Leave him. He's going to need some time to register this."

"Jesus Christ," House said, breathing out heavily. After clearing away all the equipment they had used the two men left the room and went up to Wilson's office. House sat on the sofa while Wilson took his usual seat behind his desk. They didn't speak for a while but eventually Wilson broke the silence.

"How long's he been like this?"

"About a week."

"We need to run some more tests – for one thing I'm still trying to believe I'm not hallucinating, but we also need to work out when he…. Conceived." Wilson looked shocked to hear himself talking about a man conceiving.

"I think I'm the only one who needs to worry about hallucinating."

They continued to make strained conversation for the best part of an hour before the door opened and a bedraggled looking Chase walked in. "Hi," he said lamely. He looked uncertainly at House. "Sorry I shouted at you."

House scooted over slightly on the sofa and held an arm out, inviting his lover to sit down. Chase sat next to him and House wrapped his arm around the blonde's shoulders, holding him tightly. "Where've you been?"

Chase fidgeted with the hem of his shirt. "Roof." House rolled his eyes – the roof was Chase's favourite place to escape to when he needed some time alone.

"We need to run some more tests," House said gently.

"I know."

"You want to get it done now or wait a while?"

"May as well get it out of the way."

"Ok."

Several hours and tests later, the three of them were sat in an empty lab. "The tests look fairly conclusive," Wilson said, looking through the pieces of paper in his hands. "Beta-hCG marker is present – with no evidence of testicular cancer – foetus length is approximately 19mm indicating the date of conception is around eight weeks ago, give or take."

House and Chase simply stared at him for a few minutes before Chase shook himself. "Wow. I'm pregnant."

House let out a choked laugh, and Wilson smiled slightly before he sobered up again. "You need to consider your options. We can give you a dose of Methotrexate, you'll need to stay in the hospital for 24 hours after it's administered and the success rate is high. If that doesn't work, we can try surgery."

Chase sat shaking his head, unable to process everything he'd heard that day. "I need to go home."

"I know it's hard Chase, but you really need to think it all through carefully."
