Illyana's ego hurt worse than the wounds engraved into her side. Crawling back to you was something she never imagined herself doing. The two of you ended on bad terms because of her. Her self-destructive tendencies ruined what you had and drew you guys apart. It always ruined everything, which is why she was better off alone. That is what she thought until her gashes were so bad that she couldn't bear it.
It was a simple mission, one she shouldn't have messed up so badly, but of course, Illyana got cocky and let her guard down. She ended up with nasty wounds that she couldn't treat on her own. With the little knowledge she had and the pain that shot up her body every time she moved, she had no choice but to go to you. When you two were dating, you always patched her up so you had experience. Plus she didn't really know anyone else who'd be willing to help her.
Using her stepping discs, she teleported herself to your apartment. Illyana immediately collapsed, her hand clutched at her side. She glanced up, meeting your confused eyes.
“A little help.” She mumbled, her voice filled with hurt pride.
