Here's chapter 4 final chapter. Disclaimer: I don't own Mork & Mindy.

Mindy's POV: I am so excited our Quad date today. I explain to Mork about the date. He is rather excited. Tasha and Peter will be in uniform. I can't wait to see Taylor's boyfriend. I get Mork prepared. I tell him, "Now remember, be on your best. These guys are my friends. After lunch, we will all come here a play a few games." He nods. I really am starting to enjoy being around him. I get into the clothes I had picked out yesterday for this date. We get into my car and I drive over to the meeting place. I see Taylor and John along with Peggy and her boyfriend. "So the only couple we're waiting on Tasha and Pete. By the way, this is Mork." They say Hi to Mork. Finally, a marked lieutenant car pulled into to the parking lot. Peter and Tasha got out. Peter is wearing sunglasses. He takes them off. "You are the cop who arrested those burglars." Mork said.
"Yes, yes I am." "Billy? I haven't seen you in a few years. How have you been?" Pete exclaimed.
"I've been fine." Billy Replied. All of us looked shocked except two said people.
"Wait, you two know each other?" Peggy asked.
"Yes, ever since training." Billy said.
"Tasha, Peter; this is Mork." They shook hands.

Epilogue: They went in, had lunch, and went to Mindy's to play a few games. After that day, they had started doing this more often, except games at different houses.
Peter and Tasha's relationship grew more serious, to the point where they are engaged, their wedding is getting closer.
Peggy had a rough marriage with Brian, which didn't last long. When she started dating Billy, she wanted to be sure that she wouldn't go through what she had with Brian. They are pretty close to being engaged. Her child really likes Billy.
Taylor and John were starting to get serious, then he started doing drugs and Taylor was forced to lock him in jail. She has since found a new guy, and they are now in a serious relationship. He is starting to get ready to propose.
Mork started to enjoy his new friends. He has taken police advice from Pete, Tasha, and Taylor. He started growing more fond of Mindy. Because of the Quad date, Mindy's friendships grew, significantly. She also grew more attracted to Mork. And They will be married in the later seasons.
