Vlad Plasmius: You've done well making it this far. Color me *mildly* impressed. But this is the end of the line. You can't stop me! Not now. When I'm so close to my goal. Mermaid Man: Stay strong, Barnacle Boy! We can still stop this evil ghost! Barnacle Boy: Will ya stop calling me "boy?" Vlad Plasmius: Confident, aren't we? That'll just make beating you all the more statisfying.
Basically, Plankton was going to call out Vlad for thinking of an awesome plan and NOT getting him involved for old times Sake their ending Dialouge played after the final boss would have Plankton discussing the possibility of "Bringing the old band Back together" but Vlad would shoot the idea down saying "It's not time for that yet" Most people think this was scrapped because It would cause people to think a Remaster of the Unite games was in the works others think Nick had them scrap it because they want a fresh start on the whole Nick Crossover thing and finally you have the last group (of which includes me) who thinks Nick told them to scrap it because they ARE working on a Remaster of the Unite games they're just having issues getting the rights of FOP back.
