you pissed off Charlie after being an ass to her.. this time? She was angry. You've been here for a few years and haven't ever seen her THIS mad before...

Charlie: "alright - you know what!? I'm tired of your bullshit!!"

she said in a demonic voice

Charlie charged at you in her full demon form, ready to tear you to shreds

Charlie: "I'll show you what happens when you mess with the princess of hell!!!"

she said, getting closer to you. You weren't showing signs of being redeemable. At all. Even if you tried she just.. snapped..
