"Oh, that's good," Jemma replied, "Was she feeling better?"

"Much better," He answered.

They all left the room.

May told Coulson that Lily was gone and Fitz and Jemma told the rest of the team. After a while, Jemma was doing an experiment. She wasn't feeling that great. Her head was aching and her throat was sore. She decided to take a break from what she was doing for a few minutes. She walked down to the kitchen to get some water. Suddenly, she felt dizzy. She tried to reach the wall to steady herself, but it was too late. She fainted. Fitz came out of the kitchen to find Jemma on the floor unconscious. He picked her up and carried her to the lab and set her down on a cot. He checked her temperature. 102, the thermometer read.

"Oh Jemma," Fitz sighed, "It seems you have the flu."

Jemma woke up a few minutes later.

"What happened?" She asked. looking around groggily.

"You fainted," Fitz told her. "You have the flu."

"I can't be sick," She groaned, "I have to finish my experiment."

"I'll finish it for you,"He said gently, "You've got to get some rest. I'll get you anything you need, just call me or text me."

Jemma sighed but reluctantly went to bed.

Fitz was working on the experiment when his head began to hurt. He popped some aspirin and continued working. After a few minutes, he heard May's voice.

"Jemma!" She called, "I've found some information on Mary."

She popped in to find Fitz working on an experiment.

"Oh, Fitz," She said cautiously, "Did you hear any of what I said?"

"Yeah," He said, confused, "Who's Mary?"

"I shouldn't have said that," May muttered to herself.

"Who's Mary?" Fitz repeated.

"That's between Jemma and me," She told him, "Where is she?"

"She caught the flu from Lily," He answered, "She's in bed."

"Oh, poor thing," She said sympathetically, "I hope she feels better soon. I can help her if she needs anything."

Fitz was taken aback by the fact that May was so sympathetic. Her willingness to help almost seemed unnatural. He decided that something must be going on between Jemma and May. If May wouldn't tell him, he would have to find out from Jemma.

He was walking over to Jemma's room when he felt a sudden a wave of nausea. He steadied himself against the wall and the nausea disappeared. He righted himself again and continued on his way. He thought that he might be getting sick, but he had to fight it off in order to complete Jemma's experiment. He reached Jemma's room and went inside. Jemma was lying down and reading a book.

"Who's Mary?" Fitz asked without skipping a beat.

She looked up from her book.

"Mary?" She asked.

"May mentioned her by accident," He told her, "She said that she found some information on Mary. Who is she?"

She started to cry and Fitz stepped back. He hadn't expected her to start crying. Maybe this was bigger than he thought.

"Mary is my sister," Jemma sobbed, "She was kidnapped when she was three."

He stared at her in horror. Jemma had a sister? She had been kidnapped? This was all so much for him that he had to sit down. He sat down on the edge of her bed.

"It's alright," He told her, "It's going to be okay."

In a few moments, she stopped crying.

"Thank you for comforting me," Jemma told Fitz.

He smiled.

"Of course."

He suddenly collapsed into a coughing fit.

"You're not getting sick, are you?" She asked, looking concerned.

"I'm fine," He said when was able to speak, "Some saliva went down the wrong pipe."

"Are you sure?" She asked, "You look kind of pale."

He was about to say that he was fine again when he collapsed into another coughing fit.

"You're not fine," Jemma told him, "You're sick."

She reached over and felt his forehead.

"You feel hot, even to me!" She exclaimed, "You've got to go lie down."

"But I've got to finish your experiment!" Fitz protested.

"That experiment can wait," She told him gently, "You have to go to bed."

Fitz finally conceded and went to bed.
