Well, it's not really a spoiler as much as speculation.
Scylla is the name of the electronic "black book" of The Company (tm)
Scylla is also a Greek mythological monster that had 6 heads. Supposedly, Odysseus had to sacrifice 6 of his men to get past Scylla.
It was heavily hinted that such might be the case with this "Prison Break" scenario.
Let's say that rang true. Who would be the top 6 to be knocked off to fulfill this "prophecy", if it were to happen...
Please only pick 6 (i miss the old old TrekBBS polling system -- it was SO great!)
