Farscape: Bad Timing

Braca informs Crichton and the rest of Moya's crew that the Scarrans plan on invading Earth to retrieve the flowers destroyed on Katratzi. Crichton discovers a way to fold a wormhole in on itself and permanently close it. With the help of Pilot, Crichton does just this, destroying a Scarran Stryker in the wake. During a restful trip while Moya heals, Crichton proposes to Aeryn. She accepts but then the pair is attacked by an unknown craft. Their friends on Moya look on as both of them crystalize and shatter.
