- Chuck Billy's one-time little sister, Mariana, who was in fact a star that came down to Earth as a human baby born from his mother. However, she died very early in her life, and thus turned back into a star and returned to the sky. Since then, she has always watched over her human parents and brother and, in one of Chuck's birthdays, she was authorized to come down from heaven to give him a gift: the warm light of hope, that Chuck would forever carry within him, as he would always know that Mariana would always be there - now, in the future, as his daughter with Rosie Lee.
- And this scene from one of the movies (see The Movie), which doubles as a Tear Jerker.
- The cover story from the pre-reboot #157 had a Jerkass womanizer promising Monica to go out for an ice cream and then showing up at the promised spot with another girl. She starts crying and once Jimmy and Smudge learn of it, they go after the guy wanting to know how hard he beat her so she'd cry like that. When he says that he made her cry by purposely breaking her heart for personal amusement...Jimmy and Smudge instantly trash the guy and take Monica for ice cream.
- This strip. Both funny and "awww"-able. Translation:
Jimmy Five: Monica's a pudgy bucktooth shwimp!
Monica: You dork! You keep saying that! Tell me something I don't know!
Jimmy: I like you.
- There is a quite well-known story of the 2000's in which Monica is in a very Woobie moment after having screwed up her date with Luca, sadly remembers all of her many crushes who either couldn't deal with her temper or just didn't like her back and wonders why everybody leaves. Jimmy (who also wasn't at his best moment at that point) then answers "I'm still here".
- Then he seals the moment by promising to never leave her◊. This is a particularly sweet moment when you think of the many decades these two have been together (and with the size of this franchise in Brazil, more or less the whole country knows them and knows how much they like each other underneath all that banter), which pretty much confirms Jimmy's promise: they'll never be apart.
- Jim's passionate speech to Monica in issue #94 about how there is much more to her identity than just her teeth and that he always liked her buckteeth, but admire her for her strength and spirit. It ends with Monica feeling much better about the issues she's been having for the entirety of the story, and paves the way for them to get back together again.
