Spencer may have been a fool to have unfinished business. In the 1995 Casper movie it was said that ghosts had unfinished business. It could also have been stated in The Spooktacular new adventures of Casper. If Spencer doesn't finish all he had to do before he dies he might come back as a ghost.
If there's another character for the show that has lines after Spencer ran away it will be this. New Character: Man what happened to y'all backyard? Lana: It's a long story. New Character: I hope y'all didn't get robbed. Kate: Mom, I've been into Spencer's room, and he's gone. (As some of the original transcript continues) Leo: Mm hmm, here we go again. New Character: Man, Leo don't you tell me you did that boy dirty. Leo: We're just disappointed that he didn't finish what he started. New Character: Man you know you he's easily distracted man, he can take long breaks at random times. Leo: And that's why we sent him to his room. New Character: You did him dirty, fam. Leo: Well he did Judy dirty, he left her alone in the backyard with a treehouse half-finished. But she wasn't hurt, I was. New Character: There it is, it's always someone else's fault for what the youngest child does. Also, does building that thing required adult supervision? Leo: Sometimes. New Character: Sometimes? He might get a splinter, he might almost crucify himself, or he might cut his hand off with a saw. Leo: Okay let's not go too far. New Character: Fine. Also y'all better be lucky CPS wasn't called if that happens. Leo: No, no, no need to get them involved, we're perfectly fine. Lana: You really think we're that rough on our son? New Character: Yeah, we better go get that boy. It's a jungle out there, he gonna be hungry, and I bet he begging for quarters at any minute, fam.
