"OK...?"

"Derpy." the mare told House her name.

"You can say that again. Are you here about your eye, cause I'm not a Ophthalmologist." House replied.

"HOUSE!" Wilson exclaimed. "You can't pick on her like one of your normal patients! Can't use see there's another reason..." But he was cut off by a muffled whimper.

"N-normal?" Derpy asked.

"Oh great you made it cry..." House complained.

Just then Taub came into the room.

"Sorry to interrupt but we need you in the meeting room." he said.

"Awww man, well I'm sure Wilson wouldn't mind taking over." House replied. "Thanks Wilson."

"But!"

Wilson was cut off by the closing Door of Exam Room 3. "I guess it would kill him to do his job..."

"How was the blood work?" House asked as they walked down to the hall where the meeting room was.

"Well.."

"What Dr. Taub? She have a high midiclorian count? Cause if that's the case, Get her to Master Yoda we must." House interjected impatiently.

"There was a high level of blood cells, but one other thing." Taub answered.

"OK, what was this, "Other Thing."?" House pressed.

"I don't know how to explain it. It must be something only these ponies get, because I've never seen it before." Taub said.

"Great. Just what we need a vague symptom we know nothing about." House commented. "Are Foreman and Thirteen back yet?"

"No." Chase answered as Taub and House entered the meeting room.

"OK then why don't you see a pony about a wallaby with bad glaucoma and we'll regroup when they return." House retorted. "Taub, I want you to study any pony exclusive diseases and conditions."

"Well I don't see anything that would suggest sexual activity." Foreman said as he and Thirteen continued their search of Rainbow Dash's house. Fluttershy, prompted by Twilight of course, had helped them get in. But it seemed that the two human doctors could not find anything that could help them.

"It's like Dr. Cuddy said. Why would these poor innocent animals be raging sex addicts." Thirteen replied.

"Or both her and House are wrong and we can go home." Foreman said throwing his hands out to his sides. Where he knocked over a pile on things. But what interested him the most was a small picture. He only saw the back it read "TS-1 Incident Evidence - Blackmail Picture #3" "Looks like someone needed an Attorney." Foreman laughed turning over the picture. "Oh God!" he shouted jumping back.

"What?" Thirteen questioned his reaction. "What could be so bad?"

"I never knew a horse could do that!" Foreman answered showing her the picture.

"Well then." Thirteen commented with raised eyebrows. "It says it was a Blackmail picture. Should we show House?"

"On one hand he torments the patient over something that already haunts her, on the other he off our asses and just poking fun at another patient." Foreman answered.

"So yes then?" Thirteen asked.

"Why not." Foreman answered. "It might be useful."

House rushed into Rainbow's room.

"So you must be into some weird stuff." He said.

"What are you-" But she stopped when she saw the picture in House's hand. "Where in Hell did you get that!?"

"The Embarrassing Photo Fairy gave it to me." House answered. "But I guess you'd know him as Dr. Foreman. I had him investigate your house for any clue that might have caused your condition."

"That's an invasion of privacy! I want my lawyer!" Dash yelled.

"What the same lawyer that defended you in this case?" House asked. "Don't bother, we had permission from your friends to search."

"Why would they...?" Dash stammered.

"Because you ponies trust too easily." House said. "So you don't suppose that the activity may have have at least caused the break in your left wing?"

"W-what?" Dash exclaimed.

"Remember the scan we took earlier? It showed that your wing bones in particular have become very brittle." House answered.

"That's impossible!" Rainbow shouted. "I am in TOP condition. Always have been!"

"Then what the Hell are you doing here?" House shot back. "Tell your friends that so I can get out of this place."

"Tch." Rainbow recoiled. "I-I have no idea if it's related to the picture. Or rather what's in it. It's like it was just there to in an attempt to make fun of me and has no real value but for you to have your shits and giggles."

"That could be possible." House said. "The Universe must really hate you."

"So could it be some weird pony STD?" Chase asked as all the Doctors sat down.

"I don't know. Why don't we ask Dr. Taub, I had him study the diseases that seemed exclusive to this world. What do you think?" House replied.

"Well seeing the umm, picture, led me to believe it could be a contributing factor. But nothing seemed to fit. Then we had to add the fact that her bones are degrading." Taub said. "I honestly think that Foreman picked up that picture so you'd make fun of the patient."

"Bone Degrading could point to auto immune." Thirteen suggested.

"What's my one rule when diagnosing a patient?" House sighed at this. "It's. Never. Lupus."  

"There are more auto immune diseases than Lupus." Thirteen retorted.

"Inflammation Perturbs can cause bone loss." Chase said.

"Good try. One problem though, she's not a Preterm Baby." House interjected. "Even then her eyes are fine."

"As far as we know. We haven't tested her eyes." Thirteen said.

"Alright, assuming that Chase's theory is correct, exam her eyes. We'll go from the results." House decided. "Class dismissed.
