I wouldn’t put it past her. 

"What does a doom cannon even...do? I don't think doom is a projectile."

"Colloquial term for anything with enough power to kill a moon."

"...there's a colloquial term for that?"

"You may have noticed that Geniuses aren't exactly the most stable people. Saves having to say things like 'Dr. TurboGrafx's Ultimate Positron Beam' and 'High-Aperture Electron Orbital Randomizer' and 'Antimatter-Fission Payload Artillery' and 'Point Nine Nine Nine Nine Nine Cee Brick Thrower' and 'Terawatt Orbital Laser Platform' and so on and so forth. You have a Doom Cannon. Dr. TurboGrafx, he has a Doom Cannon too. Mallory? She's got a Doom Cannon. Everybody gets a Doom Cannon." 

Informal Rule Of The Peerage #26: Thou Shalt Not Build Doom Cannons. Only idiots and crazies actually need enough firepower to destroy celestial objects.

"Hey, I'm a pretty healthy level of crazy and I've never wanted to blow up the moon."

"Yeah, this is one of the dividing lines between healthy and unhealthy levels of crazy."

All our jokes are thinly-veiled cries for help!

Ah, yes. Meta-humor.

"I'm pretty sure not every genius is somebody I'd want to be friends with on the internet but my sample so far is kinda pointing that way."

“Well, you had the good luck to get me.”

Avalon grins.

Now who’s playing into the stereotype?

December bows with an outrageous flourish.

“Sorry, milady, I’m sure it won’t happen again.”

He laughs–

–and is interrupted by his stomach complaining a little more loudly than he would have liked.

"So, I don't want to ask you to feed me after you already let me use your awesome secret lab..."

“- oh, yeah, the bracelet keeps you going but the damn thing doesn’t keep you from getting hungry, I’ve been trying to hammer out that issue for months now but it somehow it still keeps cropping up -”

Avalon raises an eyebrow.

More evidence for Flaw Theory, maybe?

“Maybe. In the meantime, let’s feed our poor newbie!” 

She takes a step, then pauses. 

“- actually, wait. You haven’t eaten or drunk anything for eight hours now, right?” 

"...yeah, why–"

"–oh, right."

He holds up his implant.

"I think she might need a little refresh on the nerve fiber, first, but after that – do I have to go under for it? probably, right? –"

“I can work on you so long as you don’t thrash and you’re still lucid enough to give instructions. For most of my Genius patients that means they give me install instructions beforehand and I sedate them, but if you’d rather stay conscious I can do that. We’d need somewhere to tie you down, though - for delicate nerve work I’m not going to trust your steely willpower, sorry.”

"I don't think my willpower is all that great, I just, uh–"

"...aaaactually maybe you should sedate me. Fun as the alternative would be. You didn't really sign up for the other stuff."

- I'm just going to leave the room now shall I?
