What has to be remembered is that the Doctor has long sought to reduce the size of committees, even at one time attempting to abolish the Navigation Committee. Committees of one are obviously preferable but since that was unlikely then small was the next best option, easier to control too. Lana has been reinstated and two new members elected, a clear and important step-down by Dr John, he's losing his grip, this welcome reversal shouldn't be underestimated. The new members, three elected members representing their local communities, good innit?
