"What I want is the antidote to this shrinking liquid." Rouge replied.
Amy looked at the bat sitting in front of her with some confusion. "Huh? I...I don't have any antidotes."
Rouge smirked and shook her head. "Uh-Uh-Uh, don't try to deceive me, dear. I know where you found that liquid. And I know you have it, Amy. I saw you and Sonic on the beach. There's no way he'd be small like that and go with you if you didn't have both shrinking liquid and antidote. Yeah, the guy that sold it to you, was pretty silly. If only he knew the real price of the antidote..."
"Well, uh...Even if I do have an antidote, can't you find it somewhere by yourself?" Amy asked.
"You see, Amy...This antidote is very rare. I know that to make it, a special flower needed. And it only blooms once in 150 years." Rouge said with a hand on her hip. "And I found one rich person that would like to buy this antidote for the plenty of diamonds. Do you think I could miss such a chance to get so many jewels for myself? Eh, I wish I could just steal them. But this guy has a big level of security."
Amy frowned a bit as she listened to all that. Rouge then crawled over her with a smug, which made Amy feel uncomfortable.
"Now, dear. Will you give me an antidote?" Rouge asked with a smile.
Amy shook her head. "I...I can't give it to you right now. I still have 3 days left to hang out with Sonic, and then I'll need to give him one sip of an antidote, as I promised, so he could get back to his real size."
Rouge smirked. "So, that's how it is, huh? Sorry, Amy, but the client needs the full bottle, and I can't let you spend even one sip from it on anyone else. Who knows, maybe over time, Sonic will like being small forever."
She then took out the bottle filled with that green liquid. Amy felt more uncomfortable as the images of what Rouge could do to her with this came into her head.
"Now it's your choice, Amy - cooperate, or else I'll shrink you more and keep you as a-"
"No chance!" suddenly, a loud voice was heard.
Rouge turned her head, only to get hit by a spindash from a blue hedgehog. The power of the hit caused bat girl to fall from the bed, hitting the floor. The bottle fell on the floor too, and blue hedgehog quickly broke it with one hit.
"Sonic! How did you find us?" Amy said, feeling happy to see him.
"It's not very hard to see Rouge in the air when she's not flying too high." Sonic said with a smile.
Amy then looked around and saw the entrance door. "Let's get out of here!"
"But we need to make sure she doesn't have any more of this...potion, I guess." Sonic said, looking around.
"Don't worry, I'm sure she-"
Suddenly, something flew through the half of the room, hitting the floor next to both hedgehogs. It blown up and, as a result, the room got filled with a smoke very quickly. Soon, there was nothing Sonic and Amy could see in this cave.
"Damn, I can't see anything!" Sonic said, not being able to even see Amy who was standing next to him.
"We need to get out of this place." she said as she and Sonic then quickly ran to where it seemed to be an exit.
Both had no idea where the other was, but they could only run, as they were worried about what could happen if they stayed here any longer.
Amy heard some loud sound, but she was too worried about escaping to care.
She ran fast, hoping that the exit is right there. And, luckily, Amy's hopes were not in vain. She successfully ran out of the cave, right on the fresh air.
"Phew, we got very lucky. Right, Sonic?" Amy said, looking around.
But Sonic wasn't seen anywhere.
"Sonic? He didn't leave the cave?" she looked back as she felt concern. "Wait, is he...?"
===
The blue hedgehog was lying on the floor, his head was buzzing.
"Ooooh..." was all that could be heard from Sonic as he said in his mind: "D-Did I...hit a wall?"
Everything was spinning in his eyes. The smoke almost disappeared, footsteps were heard and a spinning figure of bat girl appeared above him. She had her boots back on this time.
"Aww, the head is hurt? You poor thing." Rouge cooed mockingly as she stood and looked down at Sonic. "Ran the wrong way~?"
Sonic didn't have any strength to stand up.
"You look so tired." Rouge said, raising her right leg.
Sonic didn't say anything. He was about to lose consciousness in any moment.
"Don't worry, Big Blue. It will only hurt for a second or few." The bat girl said softly before stomping on his face.
After hitting a wall, Sonic was too weak to handle it, and Rouge's stomp caused him to pass out.
What happened next?
