When you attack Greenish, the name of the captain of the MelnormeTrader you fight may be another one.
Note that it is possible that a Trade Master and the captain/pilot are different Melnorme, so there may be no discrepancy here.
Normally VUXIntruders warp in, in combat, right next to the enemy ship, but in the full game this does not apply, presumably to reduce the difficulty level.
