Sam and Kaylee walked through the first floor, Sam was carrying a sledgehammer while Kaylee didn't need too, she would just use her fist.

"So…" Sam started to say and Kaylee sighed knowing this was going to be an awkward conversation.

"Yes" She said over exaggerating slightly while Sam chuckled.

"This thing with Kane that you need to talk to us about… uh, we aren't going to like it, are we?" Sam asked already knowing the answer to his question but Kaylee still gave him a pointed look silently saying, 'not one bit'.

"Is it something that you are 100% sure you need to do?" Sam asked softly and Kaylee looked up at the younger Winchester who she considered her younger brother and sighed reluctantly.

"Yes" She said finally and Sam nodded, knowing right then that whatever she was going to tell them, he would back her even if it meant arguing with Dean. Kaylee looked at him appreciatively knowing what was going through his head before he got out his phone and called Jo to let her know that they hadn't found anything yet.

"Okay. Call us after you check the southeast wall" Jo said to Sam before hanging up and continuing through the walls with Dean.

"Sam and Kaylee have almost done with the first floor. They haven't found jack squat, either" Jo explained to Dean before reaching a point that he couldn't squeeze through.

"What is it?" Jo asked when Dean stopped moving.

"It's too narrow. We can't go any further" Dean explained before Jo huffed before pushing herself in front of Dean so they were squashed together. Dean groaned and tried to think about Kaylee's face rather than Jo's body.

"I can fit in there" Jo said simply.

"You're not going in thereby yourself" Dean said quickly.

"You got a better idea?" Jo asked.

"We go get Kaylee and she will go in there" Dean said seriously, hoping Kaylee was close enough to hear them.

"There's no time" Jo said pushing her way past Dean and passed the gap that stopped Dean from moving any further. Jo crept through the walls, her heart beating so hard and fast and she admitted to herself and only herself that she wished she had waited for Kaylee.

"Where are you?" Dean asked through the phone as he looked at the map of the building.

"By the north wall. I'm heading down some kind of air duct" Jo explained as she balanced the phone to her ear with her shoulder and climbed down.

"No, no, no, no. Stay up here" Dean said hurried but of course, Jo didn't listen.

"We got to find this girl, don't we? I'm okay" Jo said softly as Dean sighed.

"All right. I'm heading to you" Dean said taking off and leaving the wall. Jo walked further through the wall until she reached a point that she couldn't move any further. She looked at the walls to find them oozing with black ectoplasm.

"Oh, god" Jo said before Dean heard static in the phone.

"What is it? Jo? Jo?!" Dean asked worried before hearing her scream. Dean took off down the hallway shouting her name before using the sledgehammer in the wall. He stuck his head in the wall and found her phone on the floor but couldn't find her. He left the giant hole in the wall and ran through the hallways shouting Kaylee's name.

"What is it? What's going on?" Kaylee said appearing out of nowhere, grabbing Dean's arms to steady him.

"He's got Jo" Dean said quickly as Sam ran and caught up to them.

"What? How'd that happen?" Sam demanded following Dean and Kaylee down the hallway.

"I wasn't with her. I left her alone. Damn it!" Dean shouted angry at himself.

"Look, we'll find her" Kaylee said grabbing Dean's hand but he pulled it back.

"Where?" Dean snapped at her and Kaylee clenched her jaw annoyed.

"Inside the walls" Sam said stepping in, giving Kaylee a quick warning look.

"We've been inside the walls all night. None of the other girls are there. She won't be, either" Dean snapped as they walked into the apartment they were staying in.

"Look, take a beat and think about this. Maybe we got Holmes' M.O. Wrong" Kaylee offered trying to be helpful.

"Well, we better friggin' think fast" Dean said before his phone rang. It was Ellen. Dean picked up the phone and walked away from Sam and Kaylee who were looking at the information.

"You lied to me. She's there" Ellen said annoyed making Dean turn around and face Sam and Kaylee.

"Ellen" Dean said and Kaylee gave Sam a look that said she didn't want to be here for this conversation so she was going for a walk. Sam nodded understanding.

"Ash told me everything. The man's a genius, but he folds like a cheap suit. You put my damn daughter on the phone" Ellen snapped angrily.

"She's gonna have to call you back. She's, uh, taking care of feminine business" Dean lied, badly.

"Yeah, right. Where is she? Where is she?!" Ellen shouted when Dean didn't reply.

"Look, we'll get her back" Dean said quickly.

"Get her back? Back from what?" Ellen asked worried and angry.

"The spirit we're hunting… It took her" Dean confessed reluctantly.

"Oh, my god" Ellen said emotionally.

"She'll be okay. I promise" Dean promised firmly.

"You promise? That is not the first time I've heard that from a Winchester" Ellen mocked bitterly.

"What?" Dean asked confused.

"If anything happens to her…" Ellen threatened.

"It won't. I won't let it. Ellen, I'm sorry. I really am" Dean apologised.

"I'm taking the first flight out. I'll be there in a few hours" Ellen said before hanging up on Dean.

"Damn it" Dean shouted

"Don't beat yourself up, Dean. There's nothing you could have done" Kaylee said walking back into the room after taking a walk.

"Tell me you got something" Dean begged but Kaylee shook her head regretfully. Dean sighed and reached out to hold her but Sam spoke up first.

"Uh, maybe. Look. If you look at the layout of the Holmes murder castle, There's other torture chambers inside the walls, right? But there's one we haven't considered yet… the one in his basement" Sam explained making Kaylee and Dean look at him confused.

"This building doesn't have a basement" Dean said simply.

"You're right. It doesn't. But I just noticed this. Beneath the foundation, it looks like part of an old sewer system. It hasn't been used for…" Sam explained before Dean interrupted.

"Let's go" Dean said quickly before Kaylee stopped them.

"Hang on a second" Kaylee said.

"Why?" Dean snapped impatiently and Kaylee glared at him.

"You guys go find a sewer. I'll follow the scent of ectoplasm from the spot he got Jo. See if I can meet up with you guys or find him first" Kaylee said simply and Dean looked at her worried before nodding because he knew they didn't have time to argue about it.
