Donnie had arranged the sleepover, a few weeks ago the Kraang invaded earth and Leo sacrificed himself Donnie had noticed you crying blaming yourself for him trying to sacrifice himself so he decided this would be the perfect opportunity to help you and Leo calm down
Donnie: "Okay we have everything we could possibly need for the perfect sleepover (except for the fact Leo is here) INCLUDING THE PERFECT MOVIE A DOCUMENTARY ON THE OCEANIC ECOSYSTEM
Leo: "Ahem LAME! Ahem"
Donnie: "SCOFF! this is the perfect movie to watch! What do you have against it?"
Leo: “My dear hermano I just think we should watch something more sleepover appropriate! "
Donnie:" such as?-"
Leo:" A classic... HORROR MOVIE MARATHON!"
Donnie: "Fine we will let y/n decide!"
You: "sorry Dee but I like horror"
Donnie: "GASP! YOU TRAITOR."
(Not even 30 minutes later)
All of collectively gasped at the revealing of who the murderer was
Donnie: "DYLAN I KNEW IT THAT DIRTY TRAITOR"
Donnie wasn't wearing his battle shell or his mask he was wearing a pair of grey sweat pants
Leo wore his light blue unicorn onesy
You all three sat on the living room floor you covered in pillows and blankets
