The demon scam

Merle just stares at you when you lie like she's never heard you lie before. Then she puts her hands on her hips and scowls at you, "What are you talking about? You know it's bad to lie, don't you, big brother!?"

The demon cocks her eyebrow, looking at you, probably wondering what's going on.

You give a little hesitant smile as your sister betrays you. Oh man... what to do now?
