Sure yeah Thalia with blonde hair is cool to think about, but imagine:
Jason with black hair
He'd literally be Clark Kent.
That would rock Percy's world.
#bro I'm the hot dark haired one around here #but bro, we could both be the hot dark haired one #BRO
Everyone stared at Jason as he walked into camp. He had just gotten his hair dyed. Black. He was scared people wouldn't like it.
"Jason?" He heard Piper say.
"Yeah? You like it?" He replied with a small smile on his face.
Piper walked up and ruffled his hair. "Of course I do! You look amazing! But, what will Percy do?"
Jason was confused. Why would Percy be upset? "What do you mean what about Percy?" Jason asked.
Piper looked at him weirdly. "Um, he's been the big black haired one since forever. I just don't think he's going to react well to the whole, 'now hes not the only hot dark haired one' problem."
"Woah," Jason said. "You think he's hot?"
Piper laughed. "Well he is. But don't worry," She said at Jason's weird look. "He's not my type."
"Then whats your type?"
"You."
She kissed him and he smiled.
As they broke apart, Jason felt a tap on his shoulder.
"Seriously bro?" Percy exclaimed. "I'm supposed to be the hot dark haired one around here!"
Jason put his hands on Percy's shoulders. "But bro, we could both be the hot dark haired one!"
Percy looked at him with disgust. "Bro!"
