Let's say Worf dies, and gets selected from the Bluegill incident and is now considered to be the Bluegill Queen. If I play another copy of Worf, does he retain the "Queen" status?
I would assume yes, based on the fact that it's conferred by the Incident. So in the same way that the persona swap invalidates the Bluegill status because of the Incident's language, I would think as long as you're using the right persona, the Bluegill and Bluegill Queen designations would outlast the icy grip of death for whenever Worf rises from his grave.
I suspect that the intent was to have the personnel removed from beneath the Infestation when they died, and have the whole lot of them explode into gooey chunks when the Queen was killed, but Decipher ran out of space on the card for that much rules text. So now, you just end up with honey badger Bluegills who die and just report for duty a few days later.
Can all 7 of my personnel on the incident be Queens if all selected at some point during the game?
I initially thought yes, but after working through some logic below, I changed my mind. I don't think it works that way (see below).
What happens if all 7 of my Bluegills in play all dies at the same time (say their ship blows up)? Do I have to do 7 random selections from the incident, one for each person that died?
The wording on the Infestation is weird. It says:
Bluegill coronation text wrote:Also, when one of your Bluegills is killed, you must randomly select a personnel from here; if it matches one who was killed, that personnel was considered to be the Bluegill Queen.
I would have thought that yes, you draw once for each, but the "if it matches one who was killed" seems to imply that it's once per group, not once per individual, as you're looking to see if the queen was among them.
Otherwise it means every time a Bluegill dies, select from the incident. If your draw was within that group of one, it was the queen. I think this makes the most sense to me, and would be how I'd think to play it. Partially informed by Trek sense, partially by text parsing.
Also, the definite article ahead of "Bluegill Queen" suggests there's only one, and that the title shifts around instead of duplicating, now I think on it more. So potentially, if you draw for each individual in a group of seven of them dying, they could get
really indecisive about who's the queen before the last one dies.
"Yay, I'm the queen!" *bleaaah*
"Woohoo! Queen time!" *bleaaah*
"My turn? Sweet!..."
tl;dr It sounds like the crown passes between Bluegills, not duplicating across them, and it could potentially move any time one of them dies. A persona swap does not retain the Bluegill status if the resulting version in play is not the same as under the Incident.
Does that sound right?
