Chloe and Lucifer went to see Doctor Linda Martin, Delilah's therapist. "I'd like to ask you a few questions about Delilah." Chloe asks who Delilah was having an affair with. Linda tells the hunter that she can't tell her. Lucifer uses his powers to influence her to answer the question.
"Mmmmmmokay, it's Grey Cooper." The doctor finally says. Chloe and Lucifer head to set to see Grey Cooper. Chloe asks him questions about his relationship with Delilah. Cooper denies having a relationship with Delilah. Amanda, Grey's wife walks up and Chloe asks her about Delilah as well. Chloe notices that Grey is wearing the same watch as the shooter, and asks him where he got it. Cooper still denies his affair with Delilah until Lucifer uses his influence on him.
Chloe and Lucifer meet up with the others back at Lux. Chloe and Lucifer talk and Chloe questions how she ended up in a nightclub with the devil. While they are discussing this, a news story is being told about how Delilah's death caused an increase in album sales.
"Too bad your little protegé's not around to cash the check." Maze said to her boss and old friend. This caused Chloe to connect the dots and realize who killed Delilah. She relayed this to Lucifer and the two of them went to confront Jimmy Barnes. Chloe told the man that she knew he killed Delilah and that she knew why.
"I made her! And she ruined me! She humiliated me! She owes me!" The producer said, making Lucifer angry.
"You're not God, Jimmy. You didn't make her. But you did destroy her. So I'm going to punish you." The devil told him.
Jimmy threatens Lucifer with a gun, not knowing that it wouldn't do any good. Lucifer continues to approach him. Jimmy fires a few shots and one of them hits Chloe. Lucifer is angry, and shows Jimmy his devilish face, a face that would torment the producer turned murderer.
Chloe woke up in the hospital to Lucifer sitting next to her. Lucifer made a joke about how long Chloe had been unconscious. Lucifer left not long after Trixie came into the hospital room. Chloe made a decision about something important.
"What's up Chlo?" Dan said as he walked into his wife's hospital room.
"Sam, Dean, and them are going to be leaving soon. To stop the whole apocalypse thing." Chloe started. Dan knew where she was going with this.
"You're going with them aren't you? I won't try to stop you. Not that I could anyway. Just stay safe." Dan told her.
"Yeah, but that's not all Dan. It's time." Dan knew what she meant. He knew that this could happen from the time they initially separated. "It's what's best for both of us and what's best for Trixie."
Dan knew that she was right. "Alright. I agree." The two would file for divorce as quickly as they could, and Chloe would go with her two childhood friends and two angels to save the world.
Sam and Dean leaned against the impala waiting for Chloe to exit the hospital. She walked out with a smile when she saw her friends. Her arm was in a sling. "Hey, ready to head out?" Before Sam could get in the car, Chloe slipped past him and sat in the front seat.
"Yeah." Dean laughed at his brother's face. Dean thought 'Having Chloe around would be good for Sammy.' "Lucifer's gonna follow in his car. Can't say I blame him. It's pretty nice."
Not long after they get in the car, the boys and Chloe get a tip from Bobby about a 24 year old man, who somehow died of old age. They arrive and they all get out of their cars. Lucifer and Maze walk up to the hunters. "Why have we stopped? I was under the impression we were going to stop the apocalypse." Lucifer said, sounding annoyed.
"Why is she here?" Sam asked, uncomfortable with a demon being nearby, given how poorly working with demons had gone for him in the past.
"For one, this seemed fun. For two, I'm not going to leave him to travel with a bunch of hunters without backup." The demon told the hunter with an expression that said that she was counting the ways she could kill him. Which she was.
"Anyway, Lucifer. Yes, but we can't just ignore other monsters." Chloe said in the same tone she used on her daughter when Trixie was annoyed at having to do her homework before playing with her toys.
Dean explained the case to the devil and his demon bodyguard. Lucifer sighed. "Humans, they really can't prioritize." Maze agreed. "Alright, fine. So how does this work? You just walk up to people and ask if they're monsters?"
"No, obviously not." Sam said, mildly annoyed. Normally he wouldn't be so irritable, but Mazikeen really unnerved him. He also didn't particularly like Lucifer being there. He couldn't complain, because he was the one who convinced Dean to make a deal with him. Sam thought Lucifer was going to be more like Castiel, who sort of did his own thing until he was needed. Same didn't want to be travel buddies with the devil. He also didn't like that Dean didn't seem to really mind Lucifer being there anymore.
"Sam, are you okay?" Chloe asked him after pulling him aside. She may not have seen her friend in a long time, but she could still tell something was bothering him.
"Not really. It's that demon." Sam had always felt like she could talk to Chloe, maybe because there was a time where both of them wanted to stop hunting.
"Mazikeen? What about her?" Chloe asked.
"It's just everytime a demon gets close to us, even a little, it ends badly for us. Last time, it led me to cause the apocalypse." Sam said, relieved to have someone that would listen to him.
"Sam, I don't think Mazikeen has any intentions to even talk to you that much, let alone sabotage your life." Sam and Chloe both laugh. "But it's not just her, is it?"
"No, it's not. It's kind of stressful knowing the actual devil is following us in a corvette." Sam admitted. He felt a little better now that he told Chloe about it.
"I agree that it's a bit weird. Maybe we'll get used to it." Chloe looked up at Sam. She'd almost forgotten how tall he was. It wasn't that noticeable when he stood in the group, because Lucifer was only slightly shorter. "Hey, so where's your angel friend?"
"Looking for God." Sam said. Chloe had a shocked expression.
"I've been too preoccupied to even realize it. If angels are real, then God is too. Wow. That's- That's big." Sam smiled at her. "I guess it makes sense for it all to be real, since Hell is. But I just figured, I've never seen an angel, so they probably don't exist."
"Well, most people haven't seen a shapeshifter either, or at least not that they know of." Sam's words made perfect sense to Chloe.
"True, it's not like I could recognize an angel, just by looking at one. Lucifer and Castiel look like people." Chloe had calmed down, just as Sam was going to drop more news on her.
"Well, they're sort of in people. But apparently they have to get permission first." Chloe had too much information all at once.
"I am done with learning new things about angels for the day." Once again Chloe made the younger Winchester laugh. They went back to the group who were arguing.
"Absolutely not." Lucifer said to Dean. "Not in a million years."
"Lucifer, it's not that bad." Dean was laughing at the devil. Not something anyone expected. "It's just a motel."
"Exactly, a motel. I will not stay in a motel. It has to be a hotel, four stars at least. Five stars are preferred." Lucifer insisted.
"You'd think someone who lived in hell would have lower standards." Dean joked back.
"How about you stay here and Maze and I stay in a hotel across town?" Lucifer asked and received a stare from Dean. "Fine, but I get my own room." Sam was shocked at the sight. Was his brother becoming friends with Lucifer?
"Okay, we were going to have to do multiple rooms anyway. We can do three rooms." Dean actually thought that Lucifer was an interesting guy. He wouldn't mind being friends with him.
Chloe was good at logistics so she took charge of the next part. "Sam and Dean in a room Mazikeen and I can share, and then Lucifer gets his own." Chloe's tone showed that she was not taking any suggestions,especially from Maze.
The group checked into the motel, Lucifer still a little bitter about the state of the rooms. "Reminds me of home." Maze said, only kind of joking. Chloe and Sam did some research and Dean was watching TV. Maze was playing with her knife and Lucifer was looking for alcohol to fill his flask with. Chloe decides they should extend their search to missing persons as well, and they find someone.
Sam and Dean go to talk to the wife. On the way over there the brothers start to talk. "So you and Chloe, are you going to start that up again?" Dean could tell his brother still had feelings for their old friend.
"What? I don't know. She literally just got divorced. And Dan is our friend." Sam didn't expect this conversation.
"Okay, sure, but technically she was your ex first so…" Dean wanted his brother to be happy and he felt that Chloe could make him happy.
"I don't want to talk about this right now." Sam sighed. "How come you seem so friendly with Lucifer now?"
"Well, I don't know. He's not as awful as I expected. I thought you'd be the first to get along with him. You did convince me to work with him." Dean had a slight bitterness in his voice that revealed that he was still upset about Sam and Ruby.
"Work with him, yes, but I didn't think you'd befriend him." Sam sighed, ignoring Dean's subtle allusion to the demon.
Sam and Dean interview the wife of the missing man. Dean pretends to go to the bathroom, but actually looks around the house. He finds a receipt from an hourly hotel in the man's jacket. Sam and Dean meet Lucifer and Chloe at the hotel. Sam is working on picking the lock when they hear yelling, so Lucifer effortlessly kicks down the door. Inside is a young man with two women. They almost leave when Sam notices his tattoo.
"Are you Cliff Whitlow?" Sam asked. Lucifer gave him an intrigued look. The man denied it, but Lucifer found his wallet that had his ID in it.
"You're older than you look, I see." Lucifer jokes.
"Please don't tell my wife." Cliff asked the hunters and the angel. Cliff refused to tell them how he got younger.
"Well, we won't tell your wife, if you tell us how you look so much younger." Chloe told the man who told them about a man named Patrick who hosts a poker game that Cliff won and that's how he got younger.
"Let's go talk to this Patrick. See what he's up to." Lucifer said. The others were a little surprised at his eagerness. "The faster we deal with this, the faster we solve the apocalypse problem."
