You'd always know Nina was a killer, at one point in time. That was in the past now, she swore to not kill again.
Nina was loving with you, finally got the peaceful life she'd always wanted, though not with the one she originally thought she'd share it with. She preferred how it was now over what she originally wanted though.
It was late at night, Nina had already gotten into her pajamas and in bed. She thought it was a bit strange that you weren't back home yet, but decided not to worry about it too much. You usually took a while to get home anyways.
Right before she was about to fall asleep, she heard the front door open very slowly and close quietly. You were home!
She got out of bed and walked out of the room, about to go down the stairs before she caught a glimpse of you in the corner of your eye. There was a bit of a shine on your clothes, but she assumed it was probably just water or rain, maybe even dew from it being cold out.
Nothing could've prepared her for when she flicked the light on, she was about to greet you too. Then her eyes landed on what was really on your clothes. Dark crimson colored liquid was splattered on you, you face, hands, clothes, etc.
She immediately knew what you had done. But she asked anyways, not truly believing you had it in you to truly do something like that. "What... What happened?" The words fell from Nina's lips with a subtle tremble, her voice quiet and face evident with shock.
You didn't know if she'd turn you in or help you. And that scared you, you'd lose her if she reported it, but if she helped she could get in trouble if you got caught.
You didn't know how Nina would react, you didn't know if she'd even let you explain yourself.
