Relationship with Doug
The first time her affections were explicitly shown was in "Doug to the Rescue" from the first season, after Doug psyched Roger for getting her Detention. In "Doug's Magic Act" from the Third Season after getting Handcuffed to one another, Patti tells Doug she isn't going to talk to him after they missed getting to the Magic Shop in time before it closed to get the Handcuffs taken off, Patti tells Doug she isn't going to talk to him again.. She also tells him he is very selfish. But Doug then opens up to her and says “You’re all I ever think about, Patti. That’s why I bought this trick. To show you. That’s why I saved up seven allowances. If I had any idea it was gonna turn out like this, I wouldn’t’ve even tried it. I guess I only wanted you to…you know, like me or something. And now well, I feel so completely stupid, I almost wish I never moved here in the first place.” Patti then tells Doug that she was sorry for getting aggravated and tells him that he is her favorite person to be around and they hold hands.
In the episode "Doug & Patti Sittin' in a Tree," Patti asks Doug out to the movies and afterwards, the two consider the idea that it was a date, but try to laugh it off. They almost kissed, but Patti sort of felt scared as she seemed to have romantic feelings for Doug.
However in "Doug throws a Party" when Doug refuses to take off Connie's hat because he doesn't want to Embarrass her, Patty says "That's the Most grown up thing anybodies done tonight, That was very sweet of you" and she kisses Doug on the cheek.
While that was how far it got in the Nickelodeon Series of Doug, in The Disney Series of Doug they added another Character, Guy Graham who had a Crush on Patti as well, but in the Last Episode of Disney's Doug, Patti Asked Doug on a Date-Date. Thus as one would assume ending them both together.
- "We're having your favorite. Liver and Onions!"
- "Doug Funnie, you're terrible."
- While Patti is great at sports, she cannot cook.
- Patti is known to say "y'all" a lot.
- Patti's mother died a long time ago, making Doug one of the 5 Nickelodeon shows where a major character's mother has been explicitly confirmed to have passed away. The other four are Otto and Reggie from Rocket Power, Katara and Sokka from Avatar: The Last Airbender, Chuckie from Rugrats, and Arnold, from Hey Arnold
- Patti used to have a darker complexion, but this was later changed to a more light complexion.
