In all honesty, Viktor didn't particularly like teaching.
Then why be the assistant of a professor, most people asked? Well, he had his reasons. Probably. He was pretty sure he could find a good reason if he thought hard enough. But really, teaching wasn't really his thing. More often than not the students were annoying, restless, and frankly just silly. Viktor couldn't understand why Heimerdinger took so much pride in teaching. It was probably old age, made him soft and far more patient than Viktor himself could ever be.
The only fun part of teaching were the bi-monthly lab experiments that he was in charge of, without the little Yordle hovering on his shoulder. More often than not something went terribly wrong, like a glass vial breaking or an experiment exploding, which meant that Viktor could shoot a disappointed glare at the students involved, demand them to clean up, and even whack them lighty with his cane if he was in a particularly fine mood.
Now, second Friday of the month, Viktor and your class were in the lab, working on making an assortment of colourful fireworks after calculating the right formula all week. His eyes glanced over the nine pairs of students present before his gaze finally landed on you, all alone at your workbench and struggling to juggle all of your tasks by yourself. You were a new student, he vaguely remembered someone oversaying. It seemed that you hadn't had time to make any friends to work with in your first month here, or maybe you weren't very interested in making any.
But you were struggling, and Viktor knew that Heimerdinger would beat him with his own cane if he ever found out that he had left a student mess up because of his own lack of awareness. So he slowly stepped over to you, smiling slightly when he noticed you getting a little frantic at the sound of his cane clicking across the tiles, probably scared of a whack.
"You seem to be having trouble," he remarked once he was close enough to not have to yell across the room. "Would you accept some help?"
