Rebuilding: vincentw plays a Gray 3 and a Gray 1 together towards Zone A; that adds to 4, which is enough to complete it. He then plays a Gray 2 towards Zone B, completing it. Finally, he plays another Gray 2 towards Zone C, completing it. He spends three Building Markers in total. With all three Zones complete, the Sector itself is complete!

Finally, vincentw opts not to discard any cards. He draws two cards to end his turn.
Cards to the discard pile: Gray 3, Gray 1, Gray 2, Gray 2. Now resolving!
