Solace to the rescue
Percy: Dude, thank-you for coming!
Jason: Anytime bro, what's wrong?
Percy: There is a... thing, under my bed, and I can't get rid of it.
Jason: What kind of thing?
Percy: A horrible, dark, evil creature. It won't leave, no matter how hard I try.
Jason: When did it turn up, just today?
Percy: No, it was yesterday. It turned up on my doorstep and it looked kind of hungry, so I let it in and fed it.
Jason: And then what?
Percy: Then it disappeared... or so I thought. 'Bout an hour later, I find it in my kitchen; it has eaten everything.
Jason: Everything? Even-
Percy: My cookies? Gone. My cereal? Gone. The left over pizza from last week? Didn't even heat it. But that's all fine, really, it's fine... but you know what's not fine?
Jason: No... don't tell me it ate the... the...
Percy: Yes, yes he did.
Jason: I'm sorry, man. I know how much that-
Percy: Do you? Huh? DO YOU?! I made it all-by-my-self, and it took me hours! It was perfection! It was beauty! The perfect, exquisite layers, just the right amount of icing, not to much, not to little, not to sweet and juuuusst blue enough to be satisfactory.
Jason: Don't worry, we'll get that thing-
Percy: AND HE JUST ATE IT! I LET IT INTO MY HOME AND NEXT THING I KNOW, BAM! MY TREASURE, MY MASTERPIECE, MY-
Jason: Wait a minute... he?
Percy: I'll show you. *Leads him through his apartment*
Jason: Okay, where is he?
Percy: *Whispering* Right here. *Points down at his bed*
Jason: *Gets on his hands and knees* I don't see anyth- wait... is that... *Reaches under the bed*
Percy: Careful... careful-
Jason: *Jumps up with a yell* He... he bit me. *Shows Percy the deep bite mark on his hand*
Percy: I know, *holds up his own hands* a savage, feral monster.
Jason: We need to call a professional, now.
Percy: But who?
Jason: There is only one person that is even remotely capable of taming such a beast. *Takes out his phone, and starts to dial*
Percy: You don't mean-
Jason: Oh, I mean it all right. *Holds the phone up to his ear*
Percy: But not even that *points at his bed* deserves such a fate.
Jason: We have no choice... hello? Yes. Yes. Uh huh. Correct. Correct again. Yeah. Right at every turn. When? Now? Right now? Wait, what do you mean-
Will: *Kicks the door open* I'm here, where is it?
Percy: Right this way. *Gestures to his bedroom*
Will: Under the bed? Okay...
Percy: *Backing out the door* What a legend...
Jason: Such bravery is unheard of.
The beast: Hisss!
Will: Nuh uh, not today, big boy. You're coming home.
The beast: No.
Will: Please?
The beast: No, go away.
Will: *Stands up* Huh, it's worse than I thought... Percy, did you give it anything, as a peace offering or the like?
Percy: Well, yeah.
Will: *Eyes narrow* What?
Percy: I'm sorry! I had no choice! There was only one piece left, and he said... he said he was still hungry- *holding back a sob*
Will: It's fine, take your time.
Percy: He asked for things. Horrible, horrible things. Heretical blasphemies that he called food.
Jason: What? What did he want?
Percy: A- a- *emits a choking sound*
Jason: It's okay, Percy, you don't need too-
Will: What did you feed it?
Percy: Okay, okay. *Takes some deep breaths* A McDonald's happy meal with a frozen coke mcspider and an m&m mcflurry-
Will: You fool! Not the mcflurry!
Percy: *Breaking down* I'm sorry. After he was done, he said the burgers were smaller a- and that he was still hungry... he ate my cake anyway!
Will: *Grabs Percy by the shoulders and starts shaking him* Do you understand what you've done?! IT MAY NEVER LEAVE!! It could be leaching macca's from you for the rest of you're days!
Jason: Please?! Isn't there anything you could do?
Will: There is only one way. One way to repel the beast from your home. But to do so, we must... no, we can't. It's unthinkable.
Percy: *Groveling* Please, Will! You gotta help me, you're the only one!
Will: *A grave look on his face* Okay. I'll do it- no, we'll do it, but I warn you, what we're about to, we can never undo. What we're about to do will stay with us all for the rest of our lives, and there will be no turning back. Are you sure?
Percy: Annabeth comes back home tomorrow... if it's still here when-
Will: Say no more, if that happens, we're all doomed.
*Ten minutes later*
Jason: *Looking into the bowl, and at the demonic mixture inside* My gods...
Percy: I had no idea such evils were even physically possible to create.
Will: I know, I know, but it's a necessary evil. Percy, you get the bait?
Percy: *Timidly holds up a McDonald's cheeseburger* Affirmative.
Will: Good. You draw him out, and when you do, Jason will restrain him, and I will perform the most deadly part. *Holds up a fork*
Jason: You don't mean...
Percy: Truly you are a hero that rivals them all.
Will: It is time, lets do this.
*They enter the room, and quietly take up there positions*
Percy: *Gets down low, and holds the burger dangerously close to the beast* Hey, buddy. I got some food for yuh, wanna bite?
The beast: *Grumbles, before slowly approaching his pray*
Percy: *Slowly backing away* Here it is! Come get it.
The beast: *Eyes Jason and Will, before sliding out further*
Percy: *Carefully removes a pickle, and grimaces as he drops it in his mouth* Mmmm, delicious.
The beast: Hisss! *Lunges at him*
Jason: *Grabs the beast by it's arms, and forces it to it's feet*
The beast: *Trying to wrestle free, but failing*
Will: *Approaches with the bowl* I'm sorry, Neeks, but it has to be this way.
Nico: *Watches in horror as he stabs into the bowl, and lifts the fork, revealing a more despicable, evil, hate filled creation than any he had ever seen*
Will: You don't understand this now, but it's whats best for you, and one day, you'll look back on this moment and realise-
Nico: Please, don't do it! It's not right!
Will: I'm sorry. *Forces the home made Caesar salad into his mouth*
Nico: Mmmmm! Mmm! Mmmm!
Will: Now, I'm going to take you home, okay? Unless, of course, you want some more?
Nico: Can I have the burger before we-
Will: No. *Forces another forkful into his mouth*
Nico: Mmmmm! Mmmmm! *Coughing and chocking* EVIL! YOU ARE EVIL YOU LITTLE PIECE OF-
Will: *Forces yet another forkful of the salad into his mouth*
Nico: MMMMMM!!!
Will: Please, Nico, I don't like this any more than you do. *Raises the fork* Don't make me-
Nico: Okay, okay! You win! Just don't make me eat anymore of that horrible-
Percy: *Snatches the fork from Will and forces more into his mouth* For my cake!
Nico: Mmmm!
Will: Percy!
Jason: Stop it, man!
Percy: *Forces more into his mouth* Eat it! EAT IT ALL!
