I was watching Unification parts 1 and 2 the other day and had the thought that Riker may not have had his priorities quite right!
It was at the part where the Enterprise had gone to the storage yard at Qualor II to find where the Vulcan ship parts had come from, and where they discover that the parts should have been beamed over to the Tripoli a Hokule'a class cruiser, but in fact found the cruiser was missing and been replaced by a ship that would turn up every so often and steal the items that were supposed to go to storage
My point is that, at the time they still went after the Vulcan ship parts and never batted an eyelid that an entire cruiser had disappeared (apart from the yard supervisor).
Does this mean that somewhere out there in sector space someone has their hands on a Starfleet vessel possibly using it for piracy? Do the Romulans or Klingons have it?
Could this be a topic for a future literary challenge?
