Gamzee's got a duality thing going on, *particularly* since going crazy. His face was even the tragedy/comedy masks when he got cut in half (retconned away). Pre-peak-sopor he was excessively passive (bard/comic), then he was briefly excessively angry (rage/tragedy). Afterwards he was a deadly effective manipulator, using both smiles and intimidation for his ends. A proper bard of rage.
I want to suggest that it's actually the creepily comic, bardic half in lil'Cal. For one thing, the way Calsprite wouldn't stop laughing. The way lil'Cal is creepy and amusing like sopor Gamzee, never violent like sobor Gamzee.
Yeah, LE uses all-caps. Caliborn already does that. Arquiusprite doesn't, so the Gamzee-half doesn't need to either. Caliborn's the lord, he's in charge.
Caliborn has remarkable ability to boss people (well, puppets) around. But LE is a master manipulator. Much more a manipulator than a berserker. I think his outbursts (which don't involve purple rage electricity, just the green electricity of green sun powers) are simply because he hates Calliope. Whereas his manipulation powers are quite bardic.
Oh he also waves the wand like a conductor, not sure if that's reaching too far. Just in case, let me reach far further: Bard Quest, despite being around from the very beginning, has never actually ended. Thus, LE's immortality comes from Gamzee's bardic half.
