Quorom is not really a special case in that sense; it just tells how many nodes must ack the operation. The conflict resolution of columns proceed as usual and data replicate as usual. Node E would do the same conflict resolution as other nodes whenever it sees the write, regardless of that was because it was in the original chosen quorom set, or it was given the right a bit later in the background, or it happened during anti-entropy etc. -- / Peter Schuller
