In an AU where Percy is tasked with keeping an eye on Luke post-TLO post-HOO, so they get a 2- bedroom apartment in New Rome.
But then some magical artifact gets stolen and everyone immediately accuses Luke as the culprit. They corner him, and Luke swears up and down it wasn't him. They try to get details of his whereabouts but keeps being super vague about it.
All this commotion gets Percy's attention, so they tell him about the recent theft .
Percy: Last night? He was at home the whole time.
Piper: You can't know that for sure.
Percy: ....no he definitely stayed in his room
Frank: They said it was stolen after midnight, right?
Hazel: He could've snuck out his window...
Percy: He was asleep at midnight, I checked
Piper: (wdym you checked??)
Jason: Look, no ones gonna blame you for him escaping--
Percy: --And trust me, he was at home, in bed, the entire time.
Jason: Yeah but all night??
Percy: Yes, Jason, all night.
Everyone: ....
Grover: ...waitttt
Everyone: ????
Percy: -_-
Grover: no fuCKING WAY???
Leo: I don't get it, what's happening?
Grover: They're sharing a bed.
Everyone: !!!!!!!!
Luke: *visibly flustered* don't make it weird, it just helps with the nightmares and PTSD...
~~~
To clarify, they were up late having a long heart-to-heart convo for hours and being super emotionally vulnerable btw
EDIT: Ok maybe they were also fucking hella nasty before the hours of pillow talk. Luke is fighting for his life trying to salvage Percy's reputation but Percy doesn't give a shit, looking at Luke like "tf u talking about? I had ur cock down my throat, I ain't shy about it"
