Hey everyone so I was just thinking and this idea popped in my head so hope you guys like it. By the way this is part of Double Chase series Right after Trust no one.

I do not own lab rats only my OCs.

Leo's P.O.V

I was sitting on the couch watching tv until my mom came in. "Great news Leo," Mom said. "Did you get me that new tablet I always wanted?" I asked standing up. "No," She answered. "Oh," I said then sat back down not interested in the conversation anymore. "The news is that my sister is going out of town and needed a babysitter so I told her you'd be happy to," Mom explained. "WHAT," I screamed. I've met my cousins before and they are evil. "Why was Leo screaming?" Chase asked while him and Bree came up stairs.

"Mom is making me babysit my little cousins and they are evil," I told them. "All of you will be babysitting them," Mom told us. "What why me?" Bree asked. "Because you really think I'm going to leave Leo watching them alone?" She asked. "Fine but, am I getting paid?" Bree asked. "You might depends on how good of a job you do," Mom said. "But, why can't you watch them?" Chase asked. "Because I have to go to work and your father is working also and Douglas went with him," Mom explained.

We nodded our heads until we heard a crash. "SPIKE," Mom yelled. Spike came in to the living room. "That wasn't me," He said. "Oh yeah then who was it?" Bree asked. Once she said that Adam came running in cheering. "Can we do that again?" He asked. "Do what?" Chase asked him. "He was getting on my nerves so I just tossed him and he broke something," Spike explained. Mom glared at him. "What? Just be glad that I didn't blow him up," Spike said.

"Let's just hope you don't blow up the kids," Mom told him. "What kids?" Adam asked. Then he thought about it. "Wait Tasha are you pr-," he was cut off by Spike covering his mouth. "Well you see my sister is bringing her kids here and you all have to help Leo babysit," She explained again.

"And Adam before you ask when you babysit you do not sit on the babies," Chase told him. Adam nodded his head. The door bell rang. "That must be them," Mom said and opened the door. Then stepped in two girls. "Hi aunt Tasha," They said in unison. "Hi um," Mom said trying to figure out who's who. "I'm Rachel and that's Lisa," The slightly taller one said. "Hi," Lisa waved. "Well let me introduce you to everyone," Mom said. "You already know Leo. The tallest one is Adam. That's Bree. And those are the twins Chase and Spike," Mom introduced.

"So I have to go to work now see you guys later," Mom said then left. Bree went over to them. "So it's nice to meet you guys," She said and stuck her hand out. Rachel grabbed it and flipped Bree over. "Do yourself a favor don't get all up in my grill again," Rachel said with sass. Adam, Chase, and Spike started laughing. "I like her," Spike said continuing laughing. "Mom does always say that she watches to much K.C Undercover," Lisa said. Bree got back up. "So what do you guys want to do for fun?" Chase asked.

"I don't know aren't you guys the babysitters?" Rachel asked. "Yep and you know what Adam and I can show you two the lab. Sounds fun?" I asked hoping they would follow me down to the lab. "Sure,""Alright," They replied. "Adam you wanna come with?" I asked him. "Coming," He said following behind us. When we got down there the girls looked at the place with impressed looks. "So what do you guys think we should do," I asked them.

They looked at each other smirking. " We have an idea in mind," Lisa said with an evil smirk. I have a bad feeling about this.

Chase's P.O.V -10 minutes later-

Spike and I were playing a game while Bree was texting. "Well since Adam and Leo have this babysitting thing covered up I'm going to the mall," Bree said getting up. "What you can't just leave," I said. "Uh yeah I can I mean how hard can babysitting two little kids be," She said. "Yeah I'm with Bree on this I'm bored and their just kids we can easily handle them," Spike said.

"You know how I know this is wrong?" I asked Bree. "How?" She asked. "Because Spike just agreed with you," I told her. She rolled her eyes. "You know what I'm just going to get my jacket from the lab and go," She said super speeding to the lab and came back. "Where's your jacket?" Spike asked. "You guys may want to come see this," She said heading back down to the lab and we followed her. When we got down there we saw Adam hanging upside down by a rope and Leo tied up to a seat.

"What happened to you guys?" I asked them. Spike and Bree started laughing. I tried my best not to laugh also. "Lisa and Rachel did this to us," Leo said. "Really how did you idiots let two little girls do this to you?" Spike asked them. "They caught me by surprise," Leo said. "I just thought we were playing a game," Adam explained. "So how are we going to get him down," Bree asked. "I don't know but, I'm gonna go and check upstairs for the twins. Spike you coming?" I asked him. "Sure it beats waiting down here," He said. We went upstairs and saw the girls on the couch. They were talking. "That was fun," Lisa said.

"The fun has just begun. Those idiots won't know what hit them," Rachel said. Unknown to them we heard the whole thing.

So what are those two up to. Find out next time bye guys.
