I always thought that whatever you use to prototype a kernelsprite with pre-entry had no effect on what a sprite's personality would be. Davesprite was just dave, and jadesprite was just jade. And nothing was prototyped pre-entry in the alpha kid's session, so tons of sprites got both personalities as a result. With that logic, GCATavros definitely has both personalities. Idk, I haven't seen much of him

But Jaspers and all the trolls’ lusii sprites were prototyped pre-entry and kept their personalities
