  Einstein spacetimes in 5d that are of genuine type II in the null alignment
classification are considered. It is shown that the unique geodesic multiple
Weyl aligned null direction (mWAND) cannot have an optical matrix of rank 1 or
3. This finalizes the classification of all type II or more special Einstein
spacetimes in 5d (i.e., those allowing for an mWAND), and also proves that they
all satisfy the so-called optical constraint.
