Star Trek: Voyager1995

Captain Kathryn Janeway:
[discussing the Kazon as they walk toward the turbolift] How could they possibly have Federation technology?

Lieutenant Tuvok:
There are only three alternatives I can discern at this time. One: it is not Federation technology at all, but something similar.

Captain Kathryn Janeway:
[boarding the turbolift] Bridge.

Lieutenant Tuvok:
Two: another Federation starship may have been brought to the Delta Quadrant prior to our arrival, and they interacted with the Kazon Nistrim.

Commander Chakotay:
Were there any other reports of missing starships?

Captain Kathryn Janeway:
Not to my knowledge.

Lieutenant Tuvok:
Three: someone from this ship has covertly given technology to the Kazon.

Captain Kathryn Janeway:
Computer, halt turbolift! I don't like Number Three at all, Tuvok.

Lieutenant Tuvok:
Nevertheless, it is the most probable explanation.
