I don't own the character, JKROwling does, hope you like it.
Snape spun around when the screaming started, followed by a tremendous bang, so loud that Snape himself thought he had lost his hearing. Smoke bellowed out of one of the students cauldrons. Potters to be exact. The smoke began to grow and Snape covered his face quickly. The screaming was continuous.
"Oh will you all shut up!"
He yelled, hearing the students stop, he quickly rushed over to Potters side. The young boy was lying on the ground, his eyes, oh god no! His eyes. Potter was trying to claw out his eyes, screaming out in pain.
"Potter, stop moving!"
Snape felt dread engulf him as he saw the damage on Potters eyes. "Students, get out, you're dismissed, I've just let the teachers know why you're out", he snarled. He watched as the kids quickly grabbed their stuff and scurried out of the room. Madame Pomfrey was by his side in a flash.
"By god Severus, what on earth happened?"
"You know what happened, one of the potions backfired".
She frowned as she scanned his face, "what is this potion, I've never heard of it".
"It's because I've made it myself... I don't think you can help me".
"True, I came here for nothing".
"Not my fault the system alerts you every time".
Pomfrey patted him on the shoulder, "well, if you need any assistance I can help you any time". Snape nodded and replied with a mere, "thanks", before turning all his attention to Potter. His ragged breathing had slowed down.
"Snape?"
"Potter, that was a very stupid move of you".
"It hurts!"
Snape rolled his eyes, knowing that Potter wasn't going to listen, he was in too much pain right now. He grabbed Potters shoulder and helped him up, hearing the young boys sobbing, "come on, move along quickly, we don't have much time .The potion will do more damage to your eyes if you're too slow. He ended up shoving Potter into his quarters. The boy had managed to make his way to the couch without Snapes help.
"Stupid child".
Snape said under his breathe as he quickly grabbed a cloth, wetting it with luke warm water. He gently placed the cloth over Potters eyes, startling the boy, "don't flinch, I don't want to poke your eye out". Snape couldn't help but wince after saying that. Potter sighed, but didn't say anything. Snape went over to the armchair, his eyes never leaving Potter.
