Six, your sister, was a pretty aggressive person whenever she wanted or needed to be. You just got out of a nasty breakup and told her about it. Daring as she was, she cooked up a murder plan, which you agreed to. You went back to 'apologise' to your ex, which caused them to let you back into their house. With them now distracted, Six snuck in through their window. After a minute or two, BAM. Right across their head with a whole ass metal pole, a couple of lethal stabs and then you both BOLTED back to the car. Your sister and you went far, speeding and just making sure to gtfo of there. You drove for a few hours until finding a hotel. You and Six stayed there overnight, but spend most of it chatting and laughing.
The next morning, both of you headed to the hotel lobby. You were both sat on one of the couches. Six was looking at something on her phone before she looked up at you. "They found the body" She turned the phone to you, which, she was right, the body had been found. "We're suspects." She sighed, but didn't seem all to worried.
