Disclaimer: I don't own Harry Potter, J.K. Rowling does. I hope you all enjoyed the last chapter.

A week later, Harry sat in the Great Hall eating breakfast. It was a lazy Saturday morning, and they had the weekend free, since Hermione had forced them to finish all their assignments the previous night. Harry had collapsed into his bed, not even bothering to change out of his robes. When he reached for his pumpkin juice, Hermione gasped and exclaimed quietly,

"Harry, what happened to your arm?"

He looked at his outstretched limb and saw a large bruise there. He didn't even know he had had it.

"I hit my arm back at the Leaky Cauldron," he replied. "That must be where it's from."

Hermione nodded, but he saw a glint of doubt in her eyes. They returned to the common room and Harry settled down in an armchair to watch Ron attempt to get Hermione, who was reading a a book, to play a game of Wizard's Chess. Harry was so preoccupied with this that he didn't notice the Gryffindor Quidditch team come up behind him.

"Hey Harry," the twins said, leaning down by his ears.

He jumped and promptly fell off the chair he was sitting in. There was a thud as he attempted to grab the table to catch himself, but he ended up failing.

"Ouch," he moaned.

"Sorry, Harry," the twins muttered as he stood up. He felt slightly dizzy, and had to slump back into the chair so he wouldn't fall over.

"Get your robes," Wood said. "We're meeting on the pitch in fifteen minutes. Are you alright, Potter?"

"Yeah," he replied. "See you then."

They turned to leave, but as they were leaving the portrait hole they heard Hermione ask,

"Are you sure you should do Quidditch? You look positively peaky. And, oh my god, Harry! Your hand! It's black and blue didn't you try to catch yourself with that hand?"

"Yeah," they heard his reply.

"No one bruises that easily, Harry," Hermione said.

"I guess I do," Harry replied and then they heard him walking up towards his dorm.

The team shrugged and left. Sure enough, fifteen minutes later, everyone was out on the pitch.

After practice, the team changed and Wood cornered Harry about what Hermione had said.

"Have Madam Pomfrey check you out," he said. "I can't have a sick seeker. Better yet, we'll all come with you."

Harry groaned. When the team had finished showering and changing, the all went up to the hospital wing. Madam Pomfrey looked annoyed to see him.

"What now, Potter?"

"I've been bruising easily and been having dizzy spells all day."

"Right," she said, pointing to what she had claimed as his bed. "Up you get."

He got up onto the bed and propped himself up with pillows. Madam Pomfrey placed a thermometer under his tongue and waved her wand a few times.

"38," she muttered. "You've got a bit of a fever, Potter."

She waved her wand a few more times.

t"Potter, I'm going to be honest, I have no idea what's wrong with you. It seems whatever is ailing you is a Muggle disease. I'll call in one of the doctors that helps me figure out things like this."

She turned to the team.

"You can stay if you want."

Ron and Hermione came through the doors as Madam Pomfrey went to phone the other doctor.

"Well," Hermione demanded.

"It's Muggle," Harry said. "We don't know yet."

When the doctor arrived an hour later, the sun was setting in the early autumn sky.

"Hello, Harry and friends," she said cheerfully. "I'm Dr. Elena Wilkins. I'm going to find out what's wrong with you. Have you ever been in a Muggle hospital before?"

They looked at her, confused.

"I'm a Squib," she said. "I know about magic. Answer the question Mr. Potter."

"When my cousin broke his arm, but not for me."

"Alright," she nodded and opened a file. She grabbed a wheeling thing that had a bunch of cords as she did so. "I'm going to check your vitals and then we'll get started."

She took his temperature, blood pressure and pulse. She took the thermometer away, but left him hooked to the occasionally beeping machine. He told her what his symptoms were as she nodded and scribbled notes, then frowned and scribbled more notes.

"Have you had any unintentional weight loss?" she asked. "Loss of apetite?"

"He didn't eat much at breakfast or lunch," Hermione supplied.

Harry nodded. "I wasn't very hungry."

Dr. Wilkins nodded. "Well, Harry, I could tell you you have Mono, which would explain your fatigue and other symptoms except for the easy bruising and dizziness. But even though your lymph nodes are swollen, I don't think it's Mono that's causing it. I'm going to take a blood test and a bone marrow test."

"Why the bone marrow test?" Hermione asked,the others looked confused at why she was asking. Wasn't everything a doctor did normal? Well, maybe not everything.

"I just want to make sure everything is normal. A problem with the bone marrow could be causing these symptoms."

She turned to Harry.

"Professor Dumbledore will give you a Portkey to my office tomorrow, where we will do the tests."

Harry nodded. "See you then."

She smiled as she walked away.
