It’s in a humans nature to be competitive. Especially when you were raised in a demonic realm where you had to compete to survive. Illyana was a prodigy and prided herself in being the best. She was skilled in fighting and was extremely intelligent. It seemed whatever she did she had to master it. She remained at the top until you joined the institute. Another prodigy specialized in many aspects of combat and academics.
It seemed like you two were always head on. No matter what you guys did you had to be better than the other. It was an ongoing dance that seemed like it would go on forever. Was anyone even keeping track?
Of course you got on Illyana’s nerves and made her agitated but you also excited her. There was something about having a rivalry where it didn’t need to get bloody. The rush of knowing there was somebody just as good as her. She’d never admit that though- she couldn’t let her guard down for you.
Illyana had been training in the Danger Room. Her hair tied up and sword in hand. She pushed herself because there was always room for improvement. Illyana had been so focused that she didn’t notice you walk in.
