A Captain or Lieutenant to get you home.

"I still can't believe Nemu actually let me leave," Ichigo thought to himself as he slunk slowly outside Kurotsuchi's lab. He had no idea who he'd run into; he just hoped it was someone who would agree to show him the way to go home.
As Ichigo continued to search, he did NOT know what was going on back at Kurotsuchi's lab. It seemed that the freak show scientist was very displeased with his "daughter" Nemu. He wasn't quite done with putting Ichigo through his paces – he had quite a few more tests he wanted to run on him. But Nemu had let him leave just because he wanted to. After giving Nemu a sound thrashing, Kurotsuchi sent out an alarm to the other captains in Soul Society letting them know that a test subject had escaped. Quietly, behind the scenes, many soul reaper lieutenants and captains jumped into action.
Ichigo didn't try and hide too much. He didn't stick to the shadows since Nemu had let him go so readily. Instead, he walked casually, working his way toward the center of Soul Society, hoping to find someone who could help him. After five more minutes of walking, a small flash appeared in front of him as if out of a shadow.
The small figure said, "So you're the one causing the uproar – again."
"Uproar? I was just walking."
"I've been told to find you and return you to Kurotsuchi's lab."
"Wait a minute," Ichigo said, "Nemu held the door for me so I could leave! She didn't say anything else about me having to stay."
"Kurotsuchi wasn't done with you yet," the small captain said and stepped forward.
"Oh, there's no way you're getting me to go back there."
The captain smirked and said, "I can make you do anything I want you to do." In a blur the captain was no longer in front of him, and he was face down in the dirt with a knee in his back, and one of his arms angled uncomfortably up behind him.
"Argh!" Ichigo grunted around the dirt. "Seriously! Let me go! You can't possibly want that freaky scientist to experiment on me anymore! He almost killed me!"
"Those are my orders," the Captain said as Ichigo felt some sort of bondage device enclosing both of his wrists behind him. "I don't bend rules, I follow them." That's when Ichigo remembered the Captain that had taken him down, and he knew it was pointless to argue with her. Soi Fon followed orders to the letter, and if Kurotsuchi wanted him back in the lab, then she'd be the person to deliver him.
He relaxed slightly, knowing the more he struggled, the more Soi Fon would likely hurt him. She was Captain of the Special Forces, or at least that's what Yoruichi had told him before. "Yoruichi. She and Soi Fon were close at one time," Ichigo thought to himself. Then he felt himself being wretched upward off the ground. He was standing on his feet a moment later.
Soi Fon led Ichigo by a small chain attached to whatever was binding his hands together. Ichigo took a chance and asked, "You're taking me right back there for more humiliation aren't you?"
"I am," she said coldly.
"Do you have any idea what he's done to me already?"
"No, I don't, but if I know Kurotsuchi, I can only imagine what he's done. You must be an interesting test subject if he wants you back so badly," she said as she marched behind him.
Ichigo wanted to keep her talking, "Did he say what else he was going to do to me?"
"That information was not given to me with my orders."
Ichigo wasn't getting anywhere with Soi Fon. The only thing that was happening was he was getting marched closer the lab with each step he was **** to take. He decided to try another approach with her. "Wasn't Yoruichi your friend?" Immediately Soi Fon stopped walking. She stood silently behind him for a minute, then put her hand on his back and urged him forward again.
"I thought she was a friend of yours," Ichigo tried again.
Soi Fon stopped walking again and said, "She was my superior,"
"But she was your friend too, wasn't she?" Ichigo asked.
Quietly, "Yes."
Ichigo knew he was opening a door that might get him out of going back to Kurotsuchi's lab. If only he could play on her feelings, maybe she'd let him go, she might even possibly show him the way home.
"Have you talked to her lately?"
"No. Not since Rukia's supposed execution day. We fought that day, and I learned some truths that changed my opinion of her." Ichigo looked back and saw the faintest trace of a smile on Soi Fon's lips.
"For better or worse?"
"Better," she paused and then focused a steely gaze on Ichigo's face, "why are you asking me about her?"
"No reason, I just thought I remembered her mentioning you before, that's all." Immediately, Soi Fon's face softened at the mere thought that her former superior, whom she admired above all others, had thought about her and mentioned her to Kurotsuchi's latest pin cushion.
She looked up at Ichigo, and asked him, "Where is she now?"
Ichigo said, "I usually find her at Urahara's shop in Karakura."
Soi Fon scowled, "That idiot. So lazy, informal, too casual."
"They seem kind of close,"
"Close?" Soi Fon's eyes searched Ichigo's face for some sort of explanation.
"Like good friends or siblings."
"Oh. Yes." She was relieved to not hear the term, 'best friends' come from his mouth because she'd always considered Yoruichi HER best friend, but that was a long time ago.
Ichigo saw pain on Soi Fon's face. He asked gently, "You miss her don't you?"
She looked up at him, then looked back down. She nodded.
Ichigo saw his opportunity and jumped on it. He thought of a couple of ways he could possibly get out of going back to Kurotsuchi's lab.
