Can somebody tell me why a ship counselor sat on the bridge next to the captain? That never made any sense to me at all.
My impression is that Troi was on the bridge solely because of her empathic abilities, and not that she was a councilor.
Picard did remark once that it was rare that a ship's councilor would be a Betazed, and we never saw (small sampling) another Starfleet vessel with the councilor right on the bridge. There was a councilor on DS9, but they were not part of the command staff, we never saw one on DS9 until Erza joined the station. Voyager had no third seat on the bridge for one, and there was no obvious councilor prior to the ship being pulled into the delta quad.
