In this situation, unless you have no-quorum-policy=ignore, which I hope
you don't, you will not have any node do anything, as both partitions
are not larger than half the number of nodes.

Why don't you just stop making up situations you don't really seem to
understand and start testing? Maybe things will become clearer then.
