Rekindling of an old flame (Snape x Reader)

Chapter 23

The weeks went by faster than you wanted them to, you were so focused on work you had no time to search for the rat. Which Ron was so conveniently losing every other day he never knew where his rat was when you asked about it.
It became frustrating after days of him shrugging at you with that sad little look on his face. You hadn't gone back to the shrieking shack or to the cave the centaur claimed Sirius was hiding out in.
You thought about checking on him but couldn't risk going out there, especially with Severus keeping a suspiciously close eye on you.

"Lavender, why the pout?" You asked as she came in her usual smile gone she sighed and sat down. "my rabbit is gone" she said smushing her face into her right hand and staring off "oh dear I'm so sorry" you apologized gently patting her shoulder.
She smiled at you and you took your place at the front of the classroom as the last few students trickled in. You waited a few more seconds before the door blew open and slammed against the wall. Rolling your eyes Severus seemingly floated past the few rows of desks and stood next to you.
The class began to murmur about Severus' presence in today's class, he looked at you with a raised brow waiting for you to calm them.

"Let's cut the chatter please!" You started
"I'm sure you're all wondering what professor Snape is doing here and what he has to do with history of magic" you said as they began to pay attention to you, also frightened to silence by the dark entity standing right next to you glaring.
"As you all know we've recently had other professors from other houses come in and share their knowledge of the founder of their house."
"Todays founder is Salazar Slytherin" You said sending a stack of blank paper out to all students along with pencils "remember not to get so engrossed with your note taking that you forget to actually pay attention" you said
"Professor Snape will stick around to answer questions if there is time remaining" you said before turning to Severus who immediately took over "Salazar Slytherin" he started covering the basics first "well write this down" he scowled.

"That went on a bit longer than i thought" you have ten minutes left of class" you said standing and rounding your desk "any questions?" you asked and as expected nobody raised their hand to ask, to scared too.
Seamus hand went up and you nodded for him to ask but he never took his eyes away from you.
"Aren't you a Slytherin professor?" He asked
"I am" you smiled "why didn't you give the lesson yourself?" He asked as others agreed. Severus rolled his eyes and crossed his arms while you gave an explanation as why you didn't.
"Professor Snape is the head of Slytherin house so I thought it would be more appropriate he gave today's lesson". "He has more knowledge of his house as well" you finished when another hand went up "are all Slytherins bad?" Dean asked
"Um no, not all Slytherins" you said gently touching Severus arm not wanting him to go off on the boy "some just run with the wrong crowd and make it hard for others, it's just best not to put them all in the same category" you said "are all gryffindors nice?" You asked and he shook his head no "you don't let that small bad bunch spoil the rest of your house do you?" You asked and the gryffindors in that class said no "don't let that bad bunch of Slytherins speak for the rest of them; some are only hostile because of the way other houses treat them, try being a bit nicer to them" you said hoping to have made sense.
"Okay class dismissed!" You clapped your hands together "you will be tested on this, don't lose your notes!" You said as they all filed out excited to head to the great hall for lunch.

"Thank you sev" you said absentmindedly as you rounded back around your desk to grade papers.
Severus raised a brow at you and watched with a smirk playing at his lips, you had yet to register what you just said and he found it amusing.
"Is there something else?" You asked looking up at him confused as to why he was still there.
Deciding to leave it at that he bid his goodbye and left leaving you to your work. Later that evening on your walk down to the library you finally realized what you had said to him, you smiled to yourself as you reached the restricted section. There you spent hours and hours up until the late evening skimming through books, trying to make sense of everything Sirius had told you.
