Call him Daddy ("step-dad" route)

"WHAT?!" You shriek.

"Ok, I know how it sounds-" Ned says.

"How it sounds is insane! I'm not gonna play this sick game, you fucking creep!" You shout.

"Ok look, it's not as fucked as it sounds, alright? I'm not actually replacing your dad or something," he tries explaining.

"You're crazy," you respond, clearly overloaded by all this.

"I have the powers of a god, dipshit. You'd go crazy too. And remember before you shout at me again that I have you by the balls. I could make all this way worse if I choose to. Now, are you done throwing a fit so I can explain myself?" Ned asks impatiently.

You take a deep breath. His threat was accurate and effective. Technically, what's stopping him from making you commit a crime or jump off the roof? The guy may have some humanity left in him, but he hasn't displayed much thus far. It may be in your best interest to hear him out before screaming at a magical sex pest with a hate boner for you.

You sigh, "Yes, sorry. Please explain."
