So, I've been doing a lot of research, and the consensus everywhere seems to be that Nana (aka Althea) was the one who lived in Monica's apartment, but then there's a contradiction of when Monica said the grandmother who lived there moved to Florida, and we all know Althea was in New York, so I have tried to answer that question in this chapter. Cheers!

"It's Janice," Chandler said suddenly. "It's got to be Janice."

"Why?"

"I dunno. It always seems to come back to her," Chandler moaned. "Didn't you see her yesterday? Her face was swollen to the size of a melon..."

"She was crying over you," Monica pointed out.

"I am still trying to understand why," Chandler mused. "I kept getting back with her and dumping her, and she is now married and having a baby."

"What unfinished business would you have with her?" Monica asked, confused still.

"I don't know," Chandler said, banging his head on the kitchen table.

"Can you pass the juice?" Rachel asked Joey, who obliged. Monica and Chandler were sitting opposite each other as was Joey and Rachel. Nana was still sleeping.

"I think mine is all that stuff with my mom," Monica said. "We never really talked about it and sorted it out."

"And how are you going to do that now?" Chandler asked.

"I don't know. There is no manual for being dead, so I don't have anything to go by," Monica shot back.

"So, what are you gonna do about Ross?" Joey asked. He felt the need to say something. Rachel looked so depressed.

"I don't know. I almost called him last night, but the jerk wouldn't let me use his phone. I guess I just have to watch him be with Julie forever," she said wistfully.

"He's stupid not to see what he's missing," Joey commented, digging into his cereal. Rachel was looking at him curiously.

"Oh, good," Nana said. "I didn't miss breakfast." Monica and Chandler stared as she walked through the table, bending over and opening her mouth as she passed by the food.

"Um, what the hell was that?" Chandler asked.

"What does it look like?" Nana questioned, wiping her mouth.

"Did you actually eat any of that?" Monica asked.

"No. I got the taste of it, though. I miss real food," Nana said wistfully.

"So, to answer my question from yesterday," Chandler started. "How do we eat?"

"You don't," Nana shrugged. "You can taste food all you want, but you don't need food to survive. You're dead, remember?"

"Yes, got it," Chandler nodded.

"What did I miss?" a voice asked. Monica shrieked.

"What?" Chandler asked, looking up from the muffin he was tasting.

"Oh, hello, dearie," Nana said. "You haven't missed anything yet. Joey is still eating."

"M-M-Mr. H-Heckles," Monica stammered.

"Oh God," he said. "Noisy girl number one." He looked over at Chandler. "And Italian guy's gay roommate."

"That is not true," Chandler said defensively. "You just never saw me bring home women because...well because...Mon, a little help?"

"Because he's a wimp," Monica finished for him.

"Oh, thanks," Chandler said sarcastically.

"The spandex says otherwise," Heckles shrugged.

"What...?"

Monica burst out into laughter.

"You're loud even in death," Heckles said, looking at her. He was annoyed.

"I was never loud," she said, crossing her arms.

"Spandex does not mean gay," Chandler said, not letting it go.

"Whatever you think," Heckles told him. He went over to sit beside Nana. Chandler was flustered.

"Maybe that's your unfinished business!" Monica shouted, getting it.

"No! No, no, no, no! I like boobies!" Chandler shouted back. "And hoohoos! I'm a booby hoohoo kind of guy."

"That we know of," Monica said, egging him on.

"Monica!"

"Can you keep it down? The Joey Show is about to start," Nana said. Her and Heckles were watching intently.

"Wait, you come here all the time?" Monica asked.

"I lived here once," Heckles said.

"Yea right," Monica snorted.

"He did," Nana said absently, watching as Joey got confused by something.

"What?!"

"We were roommates once for a few months after your grandfather died and before I moved away. That old bat mother of my son in law's kept at me to go down to Florida, so I gave it a try. I didn't like it very much, so I came back. I didn't want to uproot you, though, so I got a different apartment."

"And Heckles?" Monica asked.

"He moved to the apartment downstairs," Nana shrugged.

"Were you two ever...?" Monica started. Then she winced. "Wait, no, I don't want to know."

"Twice a week," Heckles answered anyway, serious.

"Twice a...oh God," Monica said, feeling faint.

"It was an itch I had to scratch," Nana said. "The thrill afterwards was worth it."

"I'm gonna be sick," Monica said, clutching her stomach. Chandler was examining them with a tilted head and a curious expression.

"Always the same thing. I never was interested in mixing it up," Nana went on. Monica choked.

"Huh," Chandler said.

"She just had to have the stuff," Heckles added. Then he chuckled.

"Oh my God," Monica said loudly.

"What's wrong, dear?" Nana asked. "Can't two people just have a little fun?"

"I just...I don't like picturing it," Monica answered.

"Well, I wasn't very spry," Nana agreed. "But I was very quick and good at it."

"No one ever saw," Heckles chimed in.

"When you moved back, did you two start...doing it again?" Chandler asked, curious.

"No. I just did it alone," Nana answered. "It wasn't as fun, but it just was a habit that was hard to break." Chandler wanted to laugh. So hard.

"I think I know way too much personal information about you," Monica said. She felt very, very nauseous now.

"What do you mean? You always knew I did it," Nana said.

"No! No, I didn't," Monica shook her head.

"You used to bring them to me when you were younger," Nana went on.

"I brought you men? Oh God," Monica moaned.

"Whatever are you talking about?" Nana asked, confused now.

"What are YOU talking about?" Monica countered.

"The sweet n' lows," Nana replied. "What else would I be talking about? I stole them all the time. Heckles helped me for a bit." Monica just stared at them. Chandler finally burst out into hysterical laughter.

"I have never felt so relieved," Monica said, sinking down in the chair. Rachel and Joey were in the background talking about something. She had tuned them out long ago. Only Heckles seemed interested in what they were doing.

"So what's your unfinished business?" Chandler asked Heckles. "I learned a little bit about you when we cleaned out your apartment. You always found something wrong with a woman and ended up alone."

"He was terrible!" Nana cut in. "He'd go on a date and come back all 'She had a wart on her nose.' 'She had one eye higher than the other.' 'She smelled funny.' The man couldn't ever just let things go. He was almost 20 years younger than me but never been married."

"I'm still learning what my unfinished business is," Heckles said once Nana had stopped talking. "I'd appreciate it if you didn't stick your nose into it. I have an idea, and it's mine."

"He doesn't have a clue," Chandler said, squinting at him.

"I could have a clue," Heckles countered.

"Okay, well, sitting around here all day isn't going to solve what our business is," Monica said, getting up. "Bing, let's go." Chandler reluctantly followed her out the door.

Joey & Rachel

"Is it cold in here or is it just me?" Rachel asked, rubbing her arms. Joey looked around.

"I don't feel anything," he shrugged. She went over to the thermostat and saw that it was normal temperature.

"I don't know what to do today," she said. "I have no idea what's going to happen to me or this place. I can't afford it on my own, and I can't bear to leave either."

"You could advertise for a new roommate," Joey suggested.

"I don't know," Rachel said. "That seems like it would replace Monica somehow."

"She would disagree," Joey told her. He was hoping Rachel would bring in a hot girl he could sleep with. She wasn't getting his hint.

"I'm not bringing in some girl for you to sleep with and ruin our relationship," Rachel said, narrowing her eyes at him. Well, maybe she was smarter than she looked. Joey grinned.

"All right," he said. Then he sobered up. He felt guilty for being happy about anything or laughing out loud. His best friend was gone. He didn't want to feel happy without him.

Chandler & Monica

"Are we just gonna sit here and stare at your mom all day?" Chandler asked, annoyed. "I have unfinished business too, you know."

"Then go," Monica dismissed.

"I don't want to go alone," he said, his voice a whine. Monica rolled her eyes. Her mother had actually been crying. Monica didn't think her mother would be so sad about her death, but maybe she was wrong. Monica had no idea where to start.

"I'm afraid you'll have to go elsewhere for you unfinished business," a voice said, making Monica jump.

"Pop Pop!" she shouted, rushing to hug him. At least you could hug and touch another ghost.

"Hi, sweetheart," he said, smiling.

"Why are you here?" she asked.

"Oh, I like to spend time with my daughters," he said. "I never did get to spend a lot of time with them, especially your mother, so that was my unfinished business."

"We can't have the same person as our unfinished business?" Monica asked.

"Apparently not," Pop Pop shook his head.

"Why are you still here if you knew what it was?"

"I didn't want to leave," he replied.

"You and Nana both," Monica noted. "Don't you visit her?"

"Oh yes. We do live together. I wish we didn't have to stay in that awful apartment, though," he sighed.

"Wait, you live there too?" Chandler asked.

"Oh yes," he nodded. "I get up early to get to one of the girls' houses before they wake up so I can watch their whole day. She'll sometimes come with me, though, and I'll sometimes stay with her. Today, she wanted to hang around for you guys. I'm sorry I didn't see you yesterday or last night. I got in quite late."

"What's with Heckles?" Monica asked.

"A lonely, lonely soul," Pop Pop said sadly. "I believe that having friends was his unfinished business. I know he and Althea lived together for a few months, but he didn't open up to her then much. I'm hoping he will with us soon." Monica noticed her grandfather was wearing his policeman's uniform. It did make sense since that was what he was wearing when he had his heart attack at work. Judy walked through her then, and Judy sneezed hard after.

"I will never get used to that," Monica commented, patting herself where her mother passed through.

"Can we go now?" Chandler asked. "I have to figure out my business too."

"I know, I know. You won't shut up about it," Monica muttered. "God."

"Nice outfit," Pop Pop said, finally noticing Chandler.

"Oh, thanks. Lucky me for wearing it when I died," Chandler said sarcastically.

"Better than nothing at all," Pop Pop pointed out.

"Oh God," Monica said, covering her mouth to hide her grin. She could only imagine.

"I will see you later," Pop Pop said, smiling back at her.

"Okay," Monica said, waving at him.

"I have an idea of where to go," Chandler said.

"All right, lead the way," she sighed, pointing.

Later

"I can't believe you thought the copy girl was what you needed to finish," Monica snorted as they walked back up to her apartment.

"Didn't hurt to try," Chandler shrugged. He had listened all afternoon to hear her say she missed him or something. She said nothing.

"I can't believe she thought you were gay," Monica laughed.

Well, maybe not entirely nothing.

"I'm getting tired of hearing that," Chandler growled.

"So what do we do now?" Monica asked. It was getting dark. They went into her apartment and found Rachel crying on the couch. Heckles was gone, and so was Nana.

"I guess I'll go haunt Joey," Chandler said, turning to go.

"Oh, don't leave me here with her like this," Monica begged. Chandler looked around her at Rachel.

"It's not exactly a treat for me either," he pointed out.

"Fine. Go," she sighed. "Thanks for nothing." She went to the couch and sat beside her friend. She wanted to comfort her, tell her she was all right and in front of her, but she couldn't.

"Oh, Mon," Rachel sniffed. "I miss you so much."

"I miss you too, Rach," Monica said quietly. "I miss you too."

I also learned that Pop Pop was Althea's husband (according to Friends Wikia), so his background was completely made up by me. As for Heckles, his age is unknown, so I put him in his 60s when he died. Thanks for reading! And thank you for not speculating/getting ahead of me so far :) I appreciate it.
