This happened because Jaime specifies what 'first thing in the morning' is to Bart at one point. I thought maybe there had been previous misunderstandings.
~Unassailable Heart
Jaime Reyes slumbered peacefully, the floor tinged with late night moonlight coming in through the window. All was quiet and still.
"Hey Jaime."
Jaime's eyes popped open, and he cautiously rolled over, only to be confronted with a dark figure standing by the edge of his bed.
"Aiiiee!"
The figure stumbled back, surprised by Jaime's scream, and Jaime was out of bed and armored up in seconds.
"Dude, don't shoot!" yelled a panicked but familiar voice. Jaime retracted his sonic gun.
"Bart? Why are you in my house?"
"You left the back door unlocked."
Jaime sat down on his bed, dropping his head into his hands. "Who tries the back door? And why are you here in the middle of the night?"
Bart shrugged in the darkness. "It's four thirty in the morning already."
Jaime lifted his head up. "Bart, I told you to come by first thing in the morning," he began.
"Yep."
"And you came by at four thirty."
"Yep."
"First thing in the morning for me is like, ten!"
"…..Oh. Well, be more specific next time-oof!" Bart was cut off as something hit him in the face.
Jaime grabbed a blanket and threw that at his friend too. "Pillow, blanket, floor, sleep. And we will not be continuing this conversation in the morning, hermano; we are going to pretend this never happened. Every time you come over, weird things happen that only are normal to you, it's like I step into some weird alternate dimension!"
"Um, aren't your parents going to wonder why you suddenly have someone over?" Bart asked, stretching out on the floor.
Jaime lay back in his bed. "Nah, all sorts of weird things happen when you're a superhero. Oh, and the fact that I might turn into a supervillain, probably isn't the best breakfast conversation."
"I get breakfast?"
"Don't make me throw another pillow at you."
"Well actually, your floor is a little hard, so another pillow might- oof!" a second pillow hit Bart in the face.
"Seriously, go to sleep. And never wake me up this early again."
"Ok."
