Am I the only one that kind of wished they showed a bit more of Jacques's backstory? Like, how he met Lena and Simone, why they decided to recruit him rather than drain him (he could've very easily betrayed them at some point, drained them of their life forces).
Simone and Lena explain that they needed someone to help transport people to the island, and having a ferry made that a lot easier for them. Still doesn't explain how they met.
Sort of in that same sense, I'm a little irritated that the fisherman served as little more than a red herring for what was really going on. I realize that that's standard Scooby-Doo formula (one or more person/people did it, another was good all along and their suspicious behavior was justified, and/or another was just acting normal if unpleasant) but it still felt like his scenes did little more than pad the movie.
For that matter, why didn't Simone and Lena ever think of taking his life force? He's close enough to them for Scooby and Shaggy to have another encounter with him while on a picnic at the plantation.
More difficulty in detaining him? Unlike the Scooby gang and the previous tourists who were dependent on the ferry for transport to and from the island (one reason the gang doesn't leave immediately after seeing supposed proof of ghosts besides solving the zombie mystery is that the ferry isn't operating), Snakebite Scrubbs has his own boat allowing him to leave the island at will. From what we've seen of him, he appears to be an antisocial individual and not fond of company, he wouldn't go anywhere near Simone and Lena, preventing them for inviting him over to stay at their place until the harvest moon and possibly obtaining a personal item of his to use for a voodoo doll. Maybe this also explains why he never sees the zombies either. Since he's in less danger from being sacrificed and less likely to trust the cat girls than the gang, the zombies dont feel they need to warn him.
Did Simone and Lena always plan on draining Beau's life? Was it like with the spice traders, they served one purpose for a time, then when the harvest moon came they served another?
They had a ready made voodoo doll of him along with the gang so I guess yes. The question is what would've happened afterwards if they had succeeded. Since Beau turned out to be undercover cop and his disappearance would surely bring the FBI to their doorstop. It doesn't sound likely they would had been able to keep their life draining up.
The bayou is a treacherous place. They could easily justify that he and the others had gotten lost somewhere in the swamp and disappeared, either down into the quicksand or eaten by the local alligators. It's practically a perfect cover for them.
Why didn't Beau just tell Velma about the quicksand? I know he tried to stop her and she was all "Hey, let me go!" But he doesn't even say "Wait, stop!" or "Don't go that way!" or the more ambiguous "Hold it!" He just grabs her, and when she doesn't take kindly to being grabbed, he raises a huge rock over his head like he's about to kill her.
In fact, he grabbed her twice, the first to interrogate her about her suspicions, and the second about the quicksand. After the first rough grab, it's no wonder Velma wasn't willing to tolerate the second time.
I'm guessing it's partially because of his Jerkass Fašade, and partially because he feared she wouldn't listen, given she's understandably suspicious of him.
When insisting the zombies are the good guys, did they forget the backstory about how the pirates (who seem to make up the majority of the zombie horde) forced the townspeople to walk into the swamp where they were eaten alive? The pirates' rather ghastly crime is just conveniently forgotten.
Considering they've spent a couple hundred years as freaking undead trying to deliberately scare people away so they don't also become zombies, I'd say they've earned forgiveness. For those who point out the magnitude of the pirates crime, remember they became undead which means they had to die first, so they were killed for crime and therefore have already paid for it.
Or it's simply a "I'd rather have the zombies" argument.
The gang could also consider it a "the enemy of my enemy is my friend situation." Yeah, Moonscar and his pirates murdered all the other townsfolk, but you could argue that they paid that debt when Simone and Lena killed them in retribution. Even if the gang didn't consider them to otherwise be heroes, the point is more that they aren't the ones trying to drain their life force and turn them into zombies, too. Furthermore, not all of the zombies are the original pirates—there's also some Confederate soldiers, the spice traders, and more recent tourists ensnared just like the gang was who were completely unrelated to the original crime. (Also notice that it's one of the Confederates who appears as a ghost after Simone and Lena are finally defeated to personally thank them, rather than one of the pirates.)
Velma might simply have forgotten that in the heat of the moment and was simply focused on what was happening right in front of her.
On the note of the pirate zombies, after being turned why didn't the undead pirates try and get revenge on Lena and Simone? They showed they were rather lacking in morality at the time, outnumbered Lena and Simone around ten-to-one and they have swords and guns. While I understand Lena and Simone are tragic villains, from the undead pirates POV, couldn't they have just swarmed Lena and Simone at the next harvest moon and killed them?
If any of the zombies were capable of killing/harming/stopping Lena and Simone, they would have done it centuries ago.
It's also possible they simply never had the chance, having not been able to find the ceremony, nor had rescuees as capable/lucky as the Scooby Gang.
Here's something I don't think anyone's noticed until me. Why does Lena have a slight Southern accent when she's French & lives in Louisiana? I can maybe understand Tara Strong may have been unable to do a convincing French accent, but considering Ms. Lenoir kept her French accent for hundreds of years, & Jacques has a Creole French accent from being a native of the area, why is Lena's accent different? She's not like Jacques where she was brought on after they found out about the curse. She's shown in flashbacks as having arrived there at the same time as Lenoir. Then again, Tara Strong's Canadian, so wouldn't she know what a French Canadian accent sounds like & be able to imitate that accent at least?
It could be that, while they were part of the same cat-worshiping cult, they weren't from the same part of the world—Simone could have ultimately originated in France while Lena was a more recent local convert, hence their respective accents. Alternatively, Simone has retained her original accent because she lived in isolation whereas Lena makes regular trips into the outside world and therefore interacts with people more frequently, gradually adopting her Southern accent as a result.
