The class looks on in a bored manner towards the head of the class as Professor Snape shows the class the proper way to produce the Amortentia potion. His words being drowned out as some students just read through the short description. 

"Okay, now rather then see you all fail to recreate this very dangerous potion, you'll be coming up and briefly take in the smells, feel free to share and know that there is no wrong answer to what to smell. This potion will smell different for everybody" Snape had said as he turned to the class, motioning them to come forward and smell the potion. After forming a line a few students shared what they got from it but some were curious.

"Professor how come you don't smell it and give the examples?" Ron piped up and leans against the desk as he waited. Snape had to stop himself from rolling his eyes too hard.

"Because Mr. Weasley, I've recently developed a small cold and my sense of smell is lacking at the moment, and even if it wasn't it wouldn't be any of you business what I get from the potion. The exercise is for the students not us." He said crossing his arms as Ron puts up his hands in a defensive manner. A sigh rumbling in the teacher's chest.

"Now if anybody isn't going to continue then we'll-" Snape's words were cut off by the door opening and the frame of Carman carrying bags of potion ingredients came into the far end of his vision, young Luna Lovegood helping he'd carry them in. The class quietly watched as the following happened.

"Oh I'm dreadfully sorry for the intrusion Professor Snape, but I do have those ingredients from the gardens for the next lessons potions." She paused as she sets it down and stretched her arm a bit after carrying the heavy bag. "Any particular place you wish for me to leave them?" She asked softly hoping to let him get back to his lesson sooner. Professor Snape nods and said he'll take them to the storage and asked her if she was willing to watch the class for him while he did so. Carman chuckled softly saying she would as he left with the bag to organize and put away. A moment of silence rang through the class and she coughed gently into her hand.

"So what is the potion you're working on today?" She asked softly walking over.

"The Amortentia potion Ma'am, we were actually just asking Professor Snape what it smells like to him hut he brushed it off." Hermione sighed a bit looking at the potion. "I just think it would help to have an example for though who aren't sure if some smells or normal or what it means to them." Hermione said as she rattled off a few more items that was her option and sighed. Carman tapped her chin softly before turning to them. "Well if you guys really wanted a teachers example for the potion I would happily oblige." She smiled brightly as she stepped over before the cauldron and take a small whiff. The waves of different aromas flooding her senses and feeling her body with emotions and sensations that were connected with them, closing her eyes softly and began to think of all the smells.

"Let's see. I smell...the morning air by the sea." She said softly remembering when her and Severus had re-met at the during the summer along the coast where they re-connected. She continued. "And also lavender, honeysuckle, and vanilla." She cooed as he mind switches for dates they've had to their wedding where lavender flowers were pinned in her hair, Severus wearing a vanilla scented after shave, and their cake being adorn with honeysuckle. A soft smiling forming a bit at the memory of that day. The last smell had the most powerful pack to it.

The smell of crisp white snow and sweat filled her mind as she remembered the time they both snuck away during the ball and embraced each others as lovers that very night. How they didn't get caught was completely beyond her as she focused on the memory of it all rather then the examples she had been giving to the class, her mind racing and her face heating up slightly only to be snapped out of it by Severus walking back through through door apologizing for taking so long, when in reality, It was likely only 5 minutes.

"Oh its no problem Professor Snape. I was just telling the students what I smelt when I caught a whiff of the potion" She said with a hand on her cheek attempting to hide the small amount of blush as they cute and familiar shy smiled spread across her face. Taking a step away from it she walked to the side allowing Snape to get back to his desk and to the potion, he quickly told the students to go to their seats and study the process of how to brew the potion and what sign they should look for in a failing brew. once it seemed like the students were at least half doing as he said he turned to Carman and thanks her softly for watching his class.

"Oh really it was nothing at all, I just hope I didn't overstep by sharing with the potion of course." She said briefly as they had a small conversation.

"No. Evan though I don't think a teacher's example is always required, you did help the students so I don't fault you. However I do have to ask, what did you smell this time?" Snape had asked as he leans against the table to listen. 

Carman smiled a bit and placed a finger on her chin and mimicked a thinking face. "Well, the usual Lavender, Ocean Air, Vanilla aftershave, Honeysuckles, and crisp snow in winter." She had paused with a playful smile. "And of course, Wet Stone and Chemicals." A pause followed by small laughter from the both of them, though the idea of a smile and laughter coming from the gloomy professor wasn't one that came easy or that the students could believe they were seeing, so they listen in closely as they mimicked studying the potion. "Honestly Dear, you ask me every time you brew this potion if it's the same. If I smelt differently would you make  sure that you got the same smell each time?" Carman had teased gently tapping his shoulder. "It smells the same when we first came here together and it smells the same now. It wont change unless I meet someone else which is highly unlikely." She said flashing the ring to prove her point.

"I know I know." He sighed reluctantly while running his fingers through his hair. "I ask to you to smell it because if it's the same then I know I've made a prefect brew again."  Severus had said with a small smile, this compliment being his way he flirted with her, which earned a playful slap on the chest and a 'Cheeky Bastard' from Carman before the smile took claim om her face again. 

"Well I must be off to prepare for my class, I'll be seeing you in the Great Hall." Her voice cooed before walking out, leaving Severus with a smile that just seemed to appear for her. Intoxicating him with a warmth and kindness not many see, like a intoxicating smell.
