Shego hadn't always been a villain.  Years ago she fought crime alongside her brothers in their hometown of Go City.  But unlike her brothers, Shego never felt comfortable being a hero; it was only out of loyalty to her family that Shego played the part as long as she did.  But finally, on a dark and stormy night, she crossed the line. 

The team had just busted up a jewel smuggling ring.  As her brothers secured the thieves for the police, Shego couldn't help but admire the brilliant diamonds and emeralds spread out before her on a table.  Before she knew what she was doing, she had scooped up several gems and pocketed them.  A few days later she sold them on the black market for more money than she had ever seen in her life, and at that moment she knew on which side of the law she belonged. 

Still, she wasn't ready to completely abandon her old life.  For several weeks she was both hero and criminal, fighting crime by day and pursuing her own agenda late at night.  Then one day just before dawn, Shego was sneaking back into Go Tower when she got a nasty surprise- her older brother Hego waiting up for her.  He was sitting in his usual place at the conference table with a grave look on his face.

"Where have you been, sis?"  He asked.

"Out," Shego replied.  She wasn't in the mood for another big brother lecture.  She started to walk away, but Hego wasn't about to make it easy.

"Shego, we need to talk.  Sit."

"I would, but I'm really tired," Shego replied, her back still turned.  "Let's do it tomorrow."

"It IS tomorrow, Shego," Hego replied, his voice more forceful.  "Sit."  Shego sighed heavily and sat down.

"Shego, I'm worried about you," Hego said.  "You've been so distant lately.  What's wrong?"

"Nothing," she replied tartly. 

"Now sis, we both know that isn't true," he replied.  "You haven't been much of a team player.  Your crime fighting has been half-hearted at best.  You hardly speak to any of us anymore, and you disappear for hours every night."

"I just want a life outside of Go Tower, Okay?!"  Shego snapped.  "This hero thing may be enough for you and Meego and the twins, but I want more!"

"Like this?"  Hego asked, holding up a small purple velvet sack, which contained the diamonds she had stolen the night before.  Though her heart was now hammering a mile a minute, Shego refused to give in to the panic growing inside her.  Instead, she turned it into a more familiar emotion: anger.

"You went through my room?!"  She cried.  "I should have known I'd never get any privacy around here!  And you wonder why I'm never around??"

Hego's tone softened.  "Shego, I know you've been unhappy.  But this is not the answer.  You are a hero and a member of team GO!  Let us, your family, help you GO back to who you are!"

That was the final straw.     

"ENOUGH ALREADY!"  Shego yelled with such force that it nearly knocked Hego out of his chair.  "I can't take it anymore!  I'm sick of your bossiness and your glee club attitude!  I'm sick of this tower and crime fighting and acting like a goody two shoes when I could be making a fortune!   Sorry to drop a bombshell on the happy little world you live in, dear brother, but this IS who I am!"

"Hey, could you keep it down in here?"  Meego's voice interrupted.  He and the twins were standing in the doorway, dressed in their pajamas and rubbing their eyes.  "Some of us are trying to get some sleep!"

"Meego, for once I'm glad to see you," Shego said.  "I have an announcement to make…I QUIT!!"  

Everyone gasped.  "You can't mean that!"  Hego cried.  "We've always been together!  We're a team!"

"Not anymore," Shego snapped.  "I don't need you losers!  I don't need anyone!"

"Everybody needs someone, Shego," Hego said.  "Where will you go?"

"I'll figure it out.  I can take care of myself, big brother," Shego replied.  She stood up.  "Well boys, it wasn't entirely awful growing up with you, but I'm outta here.  Have a nice life."  She headed towards the door.

"Shego…please don't do this," Hego pleaded.

Shego turned around.  Her brothers were all staring at her with sad, mournful eyes.  Shego's hard gaze softened slightly.

"Hego…"

"Yes?"  Hego asked hopefully.

"Blue is so not your color."  With that, Shego left GO tower, vowing never to return.
