In the next morning, Severus woke up feeling refreshed; This was a feeling that he had not felt in a long time. Why hadnt he felt like this before? All those nights spent in the potions classroom brewing, and now he knew he had to stop it. He needed this feeling more.
"Morning, Sev." Poppy said, after noticing he was awake. "Hungry?"
"A little bit, yes." He noticed. "Actually, a lot."
"Thats an improvement then." She said. "What would you like? Porridge? Eggs?"
"Um, eggs would be nice."
"Okay." She called for her house elf and the next minute a tray of eggs appeared on Severus's lap. He ate them all, and felt full when he was finished.
"That was really nice." He said.
"Glad to hear it. I suspect youre feeling better?" Poppy said, as Minerva walked in.
"Hey Severus." She said, cheerful. "You look better this morning."
"I feel it too, thanks." He replied, with a smile almost appearing on his face.
"So you feel better then?" Poppy asked, getting back to their conversation before Minerva interrupted.
"Yes, a lot, thanks Poppy."
"Good to hear!" She said and threw an unexpected diagnostic charm onto Severus. He glared at her.
"Sorry, it was necessary."
"Well?" He said.
"Temperature of 37.6 degrees, no headache, no chest pains." She read out off the little piece of parchment from the diagnostic spell. "With those results, I might let you leave later this afternoon."
"Why not now?" He asked.
"You just woke up, Severus. I will keep you here for observation for a couple of hours."
"But I wanted to go to lunch." He said glumly.
"If you behave, I will let you go as long as you come back here after to let me check you over one last time."
"Okay."
"Lunch is in three hours, and you must stay until then." She said and bustled off into her office.

Lunch arrived and Severus was able to attend. He spoke to his Slytherins as he hadnt had the chance to see them for three days. The staff were also happyto see him, and he almost seemed happy to see them aswell. He looked almost in a cheerful mood, well, cheerful for Professor Snape anyway. After having a wonderful lunch, he returned to the hospital wing for his check up.
"Still feel alright?" Poppy asked.
"Right as rain." He said as a big grin flashed across his face.
"Its nice to see you smile Sev." She said as she waved her wand over him. He quickly wiped it off his face.
"Dont get used to it." He said embarrassed.
"Well, your temperature is normal now, no nausea, no headache. I think you are good to go." She said, patting him on the shoulder.
"Thanks." He said, then he got up to leave, but then Poppy put her hand on his shoulder.
"Severus, please, please dont scare me like that again." She said.
"Ill try. No promises. I cant ignore the calls." He tried to reassure.
"Oh Sev." She said and hugged him. He slowly hugged her back. Then she pulled away. "Im glad youre alright." She said. Severus just grunted. He then left the hospital wind, as good as new.
