Victor.

You are Caitlin's sister, she often dragged you along somewhere on her business... Today she dragged you to the academy, sat you down on a sofa in some office with the phrase "Sit here, and please, behave decently!" and quickly ran away, naturally you did not sit in the office, you got up and went for a walk around the academy, seeing a slightly open door you looked in there, there were two guys standing near the board, one of them you knew, Jace, known to all of Piltover as a "man of progress!", but the guy standing next to him you saw for the first time, you became terribly interested in what was going on there and you quietly entered the room and stood with your backs to the guys silently listening to their dialogue...
Jace: Victor, I don't think this is a good idea, hextech is very unstable!
Victor: And I think that's a great idea, Jace...
Afterwards, both of them felt your presence and turned around, seeing you, Victor stunned and stepped back looking at you, and Jace, nervously, already grabbed his hammer in order to attack if necessary.
