"The Voyager Conspiracy" - After a probe of a space "catapult", Seven of Nine foments a rebellion that threatens to tear Voyager apart.
When Voyager encounters an alien whose space "catapult" can speed them back home, a data-overloaded Seven of Nine causes chaos when she incites a civil war then divides the crew with secret allegations of treachery and insurrection.
