Patty is probably the most girlish girl Charles M. Schulz ever put into Peanuts. Look at her body language in the first, second and fourth panels. Here she pines that Shermy and Charlie Brown don't love her, and they stage a mock fight over her to cheer her up. It works, too.
The fight in the third panel is interesting because the characters speak in order to make the fight seem more severe than it would without the text. I put this down to insecurity on the part of CMS that his abstract characters could depict motion well. I notice here that they say "What a battle" and "What a struggle" both in the same panel, which is a little awkward from a writing standpoint.
