Friend khr over on scalie.business cooked this up as an early hatchday present! It's hecking amazing and perfect and just aaaaaaaa. Completely overwhelmed by how amazing this is.

Anyway, these are two Synth hivemind "sisters" who just so happen to share a chassis pretty often. S4R1. "Sari", the more... pragmatic, pedantic, poised one, tends to take their right head and prefers the darker pink coloring. S4R4, "Sarah", is the more bubbly, boisterous, bouncy one and prefers the left side, and the lighter pink coloring. Anywhere neither of them is more in control than the other and/or they're sharing control tends to get a middle pink color (such as the middle head here).
