Heartwarming / Scooby-Doo! and the Curse of the 13th Ghost

• Daphne, Shaggy, and Scooby are overjoyed to be reunited with Flim Flam, and he's equally happy to see them, if not more so.
  • When the gang sees an exhausted Vincent, Flim Flam is the one who goes towards him first. He also promises to leave Mortimer's name out in the retellings of Asmodeus. The fact that he and Vince share a goodbye goes to show how much the past adventure truly meant to Flim Flam McScam.
    • Flim Flam says "Was no-one gonna pick up a phone?" when told that Vincent is here. This implies that one (or all) of the trio of Daphne, Scooby and Shaggy has Flim Flam's phone number and that they often converse together.
• Daphne gives Flim Flam a small kiss on the cheek when she sees the case of Losta Luck Joy Juice, undoubtedly remembering how he saved her from becoming a werewolf in the first episode of The 13 Ghosts of Scooby-Doo.
• Vincent tries to warn Mortifer about the avalanche his car will cause, despite learning how his old friend had betrayed him.
• Flim Flam was a hustler in the original series - this movie reveals that he's turned that over, has a stable job in a shop, and actually sold stuff to Daphne, Shaggy and Scooby and didn't swindle them.
• Daphne mentions selling "bottles of snake-oil" at a garage sale. What use does she have for bottles of snake-oil? She doesn't have a use for them. She kept them because they were mementos of Flim Flam.
• Vincent and Flim Flam's parting words as the former boards the plane.
  Vincent: And for ghoulness sake, Flim Flam... stay out of trouble!
  Flim Flam: No promises, Vinny!
  Vincent: (chuckles, smiling) That's my boy.
• At one point Shaggy lampshades how he and Scooby are terrified of every monster they've encountered despite it always being a crook in a costume or a hoax. At no point does Daphne ever criticise them in this film for being terrified: she, like them, has met actual ghosts, so of course the two are gonna be terrified; Scooby nearly had a breakdown because of it... and she knows it. She knows they're scared - hell, Scooby is facing the trauma that nearly gave him a nervous breakdown - but they help anyway. And she doesn't begrudge them for that.
  • Too add to it, when Daphne is rummaging through her clothes while Fred and Velma sit on the bed, Daphne mentions that Scooby has "conquered his demons... twelve of them at least..." implying that Scooby successfully managed to recover from it.
    • Shaggy mentions that Daphne, Scooby and he agreed never to talk about the 13 Ghosts. Daphne knew how traumatic it was for Scooby and she cares for him enough to not bring up his trauma again at any point. It's only when Scooby and Shaggy agree to come with them to save Vincent that she even brings it up again; because Scooby, without speaking, is allowing her too - he's agreeing to help, so he's willing to face this trauma.
• The movie opens with the meddling kids getting scolded by a local sheriff for their recent actions, including being told to they're not cut out for mystery solving and being threatened with legal action if they keep it up. In the end, however, an Interpol agent congratulates them for their hard work and suggests they consider a career in solving mysteries.
• The fact that Shaggy and Scooby are, obviously, terrified out of their minds at the thought of dealing with the Chest of Demons... again... but stop protesting when Daphne notes that Vincent is in trouble.
• The fact that Daphne trusts Shaggy and Scooby enough to let them be in charge of the computer in the back of the Van; she's seen them live through this before and knows they're competent enough to take charge of it.
• During the chase scene, Scooby and Shaggy have a pair of monster masks fall on their heads. Seeing each other, they briefly scream in terror, causing the masks to fly off. As soon as the masks are gone, the pair see each other and immediately embrace with happy smiles.
• It's implied in the film to have been quite a while - at least a year (since Shaggy mentions the "summer before School" and they're not in school anymore) - since Scooby has been around Vincent. But he is able to pick up Vincent's scent immediately when they all arrive in the crypt.
