Lets just cut to the story.
Ron opened his eyes slowly, groaning. He looked around and saw the various Bueno Nacho artifacts, prompting him to ask, "Am I in heaven?" Hearing a groan near him, he looked over to see Shego. "Sheila, are you all right?" She shakes her head like waking up from a forcibly induced slumber, looking up at him. "Yeah kiddo, I'm okay. How are you holding up?" Ron looked around nervously. "I'm all right, but where's KP?" Shego looked aside, making sure to seem upset. "I... I don't know. I haven't seen her." Ron seemed disappointed.
Shego looked back up at him after a few minutes, pouting. "So what is it about her?" Ron stumbled in his bindings, "What... I don't know what you're talking about, Sheila." "Kim... what do you see in her that makes you like her?" Ron shrugged. "We've been friends since Pre-K. Can't not like a friend you know." Shego sighed, "That's not what I meant. I mean why do you like her like her." Ron blushed a little, but gave his answer, "I... don't know. I'm not even sure its her I like anymore, I mean you've definitely grown on me... but I guess I've hoped for a long time me and KP would just grow into something more than friendship. It just doesn't feel right being around someone that much and not being able to care for them as more than a friend." Shego thought for a moment, not expecting that honest an answer. "Well, do you care for me as more than a friend?" Ron's face turned red, and he nodded slightly. "Well kiddo, there's a problem then. Can't have us both; but maybe..." Shego cut herself off intentionally, drawing out his curiosity. "Maybe what?" Shego shrugged. "Its nothing really... just thought you two were brother and sister when I first saw you. Maybe that's what you feel towards her." Ron was silent for a few minutes until Rufus popped out of his pocket, yawning.
"Hey, Rufus can save us!" The little mole rat tried to gnaw through the ropes, unsuccessfully. Ron noticed the backpack on the floor, "Rufus! Kim's backpack!" Rufus saluted his master and ran down to the sack, awaiting instructions. "The lipstick Rufus, use the lipstick!" The little pet popped into the pack and back out again in a moment, donning a nice shade of red adorning his lips. "The other lipstick," Shego said, exasperated. Rufus pulled out a stick of the makeup, and twisted the handle, exposing a high intensity laser.
He jumped up to where Shego was, and cut through her ropes, and as he jumped off to free Ron, he was caught mid air by a hand. "Woa there, Ron doesn't need to be set free yet." Keeping the Rodent in her hand, she looked up at Ron, who was confused. She lit her free hand, and his eyes opened in horror. "Shego? Where's Sheila and Kim," Ron asked forcibly. "Oi... Kid, there was never a Sheila. I was sent from the future, blah blah, fix the one mistake Drakken made in this plan, blah blah." Ron looked puzzled, "So what's that got to do with me?" "You were the mistake. Something you did completely tore the plan apart, so I was sent to change that." Finishing her sentence, she brought her hand up as if to strike Ron, who cowered. Shego looked at him cowering, and felt a cringe in her chest. She brought her hand down slowly and looked at it, glowing. Smacking herself inside, she brought it up again, her eyes closed. Rufus was about to bite her hand when she brought the plasma lit one down, cutting his ropes.
A few moments later, Ron noticed he was on the ground, and his little friend was shaking his head. "Rufus, you're okay? And how'd I get off the ropes?" Rufus pointed at Shego, who was now shaking, head facing down, "She did it." Ron got up and moved over to Shego cautiously. "Shego? Are you all right?" She shook her head, and a meek voice came out of her. "You know, I could have had the world. Everything in the world, and it could have been mine." Ron moved to put a hand on her shoulder, but it was yanked away. "You took that away from me. You and your being gentle and kind, ruined it." Ron tried again, this time his hand finding no resistance. She was sobbing now, "I can't believe I gave up the world for you." Ron moved into a full hug with her, and she tensed up. "Hey, come on now... Shego..." Ron was still awkward about saying or doing any of this; it didn't feel right comforting a villainess. She loosened up after a few moments and returned the hug, wiping her face in his shirt, making sure not to see it.
After a minute of sobering up, she looked up and put on her defiant look again. "Well, if I can't have the world, we shouldn't let Drakken either. Lets go get Kim." Ron looked puzzled as Shego moved through the signs and other things towards the back of the room, running to catch up as she got where she needed to be. "Kim?" Ron looked up at his best friend, who was bound and gagged against a large burrito. "What happened to her?" Shego looked down, "I told you, I was sent to fix the mistake. That meant splitting you two up; but I was going to be a lot more evil about it and let her hear what was going on." Kim had obviously been awake for a while, and was looking pretty steamed. Shego lit her hand and slashed the ropes and gag off in one motion. As soon as the heroine was free, she lunged on top of Shego, and got ready to punch. Ron's hand caught her arm, stopping her. "Ron, let go! I have to make sure she's not gonna betray us like she did just now!" Ron didn't let go. "Kim, she set us free, can't you give her a chance?" Kim looked defeated, and stopped moving to knock the girl beneath her out. "All right, one chance; but its now. What was it Ron did to mess up this plan?"
Shego was silent for a moment before starting. "Syntho-Drone 903 was designed to attract Kim, and then crush her when the time came. That way, when we made our move on the world, she wouldn't be up to the task of saving it." Kim nodded a little, "Yeah, it does hurt pretty bad, what he did to me..." Shego waited before continuing, "Ron here, brought her back to her senses when he said he liked you; rather, he said he was the guy out there for you. Kim looked at Ron, who was blushing, and she herself turned red. "Long story short, you kicked our butts, and Drakken obsessed over it for years. I'd been retired for years when he called me and told me to just show up at his lab. He told me to take care of Ron, and then Kim would have never stopped us, meaning we would rule the world." Shego bit her lip, expecting to get punched. Kim got off her and offered a hand. "I don't want to believe you, but something in how you said it screamed otherwise. I'll give you a shot, but one bad move and I'll kick your butt again, understand?" Shego nodded and took her hand, standing up.
Kim immediately started to leave when Shego grabbed her hand. "Wait; we need a plan." Kim turned around and thought for a moment when Ron spoke up, "Wait, Shego's been through this once, right? And she knows the deal inside-out. I say we let her do this one." Kim looked at Ron pleadingly, "I don't know Ron, what if it's a trap?" Ron shook his head, "Then we'll kick her butt." Kim shook her head. "All right. Shego, what's the plan?" Shego looked down the corridor. "Pretty much what you were going to do Kimmie, but let me handle myself, okay?" Kim looked at her funny. "I mean my past self. Lure everyone onto the roof, and I'll make sure the other me doesn't interfere, okay?" Everyone nodded and ran down the corridor.
Inside the control room, Drakken was smiling pleasantly. His plan not only went perfectly, apparently sent himself a little insurance on the buffoon. The massive antennae rose from the building, sending a command signal all over the world, activating his millions of soldiers. He was about to start ranting about how perfect his plan was when the door to the control room burst open, Kim Possible running in and knocking him into the panels behind him. "Shego!" His assistant jumped into action, ready to stop Kim, when a pair of green hands held her short. "Hey, what's the big idea?" The good Shego shouted at Kim, "Roof now, princess," before turning to face herself. The bad Shego scoffed, "What happened to the plan? Thought you wanted to rule the world?" All she received was a smile before she started for the roof, Ron having already lead 903 up there. "Guess what, been a change in plans. Turns out I found my world in something a lot simpler than conquest." The good Shego turned to face her past self as she neared the edge of the roof, and both sets of hands were ignited. They stared each other down for a while, oblivious to the scene going on behind them.
Kim had almost shot the scrambler when her ex-boyfriend knocked it out of her hands. She grew an angry look, and gave a strong kick to his abdomen, sending him across the roof. Ron had meanwhile grabbed the toy-looking device, and threw it at Kim. "Heads up KP!" She almost caught it when the syntho-drone grabbed it from in front of her. He never noticed the little pink thing that had slipped onto it. "Nice try loser. Oh, and by the way, a naked mole rat is not cool. Its gross." Just as he said that, a mad little "Hey!" came from the gun. When he looked to see what it was, it was already too late. The little rodent had sunk his overbite into the drone's protective casing, rupturing it. Kim smiled slyly at him. "Oh, and Eric," as she grabbed the scrambler from his weakened hand, "Don't insult Rufus; he holds a bit of a grudge." Kim turned to point the gun at the tower as Rufus jumped to her shoulder, not noticing the drone that had stopped melting behind her.
As the gun had been thrown, so too did the fighting between Shegos begin. Swing after missed swing, plasma bolt tossed after plasma bolt, they were in a full brawl. They didn't speak, only snarled at each other. The good Shego heard Ron shout, and turned to look; 903 had temporarily sealed his leak with his good hand, and was using his legs to squeeze the life out of the boy. Shego forgot what she was doing with her past self and blasted a plasma bolt at the fake boy. Just as the bolt released from her body, her back burned immensely, causing her to scream in pain; the bad Shego had taken advantage of her distraction and put her own bolt of plasma into her future self's back. Ron was freed from his prison as 903 exploded, but screamed as he saw what happened. "Kim! Shego's in trouble!" Kim turned to see what had just happened, and pocketed the home-mad device, leaping towards the two Shegos. Just as the bad Shego went to blast a bolt right in her future self's face, she was knocked off.
"Know what I really hate," Kim asked while Shego rubbed her head, and got up. Getting in a fighting stance, she answered, "That your date melted?" Kim smugly looked at her, "Nope," before turning her face serious again, "You." With that, Kim kicked Shego at the tower, knocking a good half of its base away. The tower began to fall just as Drakken came up the stairs. "No! My perfect plan!" he started to inch away when a foot slid out beneath him. "Oh, its just you." Ron looked at him very upset, glaring him down. "Taking over the world is one thing, but you ruined Bueno Nacho!" Drakken scoffed, "Oh you can't be serious." Ron got within inches of the mad doctor's face, "Note. Serious. Face." Becoming very nervous, the would-be world conqueror leered from side to side, looking for an escape. "Say my name." "What?" "Say my name!" Ron was demanding now. "Er, uh..." Drakken counted on his fingers, trying to recall, when it came to him, "Stoppable!" "Booyah." Having accomplished his goal here, he ran over to the good Shego, who was just waking up. "Ugh, remind me never to go tanning again. I think my back's been tanned for a lifetime." Ron took her hand and helped her up, just as sirens approached. "We better go take care of this,"
On the ground outside, Drakken was locked into the back of a police cruiser. Everyone ignored his comments about how it couldn't be over, save for Ron. "Get over it dude, its over." Kim looked at Ron slyly; she had not forgotten what Shego said about the mistake Drakken made. "You know Ron, we better hurry." Ron looked at Rufus on his shoulder and shrugged. "Hurry for what?" "You'll see." Taking his hand, Kim ran over to the moped, where Shego was already waiting. "All right kids, I'm driving." Kim looked at her confused, "Do you know where we're going?" Shego just nodded, turning her head to hide the tear that adorned her cheek.
"I give up the world for him, and she still gets the prize. Guess this is my reward for a life of crime, huh." Shego kept her thoughts to herself as she started the moped and drove off.
Just trust me that this is still a Ron x Shego story. Sorry it ends seeming so... Ron x Kim, but I had to separate these two chapters. Hopefully I'll get the last two up today. Also, sorry for not describing the fight in better detail... I'd say I'm leaving it to your imaginations on purpose, but that's not true. I just can't write a good fight scene.
