So firstly, when i watch the Sanders Sides videos, i feel like Virgil and Logan are on the left side of the room and that Roman and Patton are on the right side of the room. So i think their position in the room depends on if they are more on the left brain or on the right brain.

Also, Remus seemed to be more on the right side of the room. Janus seemed to be more on the left side of the room (if we don't count the littles scenes at the end of the episodes).
