Page "Ro Laren" Paragraph 15

In " The Next Phase ", Ro and La Forge are presumed dead after a transporter malfunction while returning from rescue operations on a disabled Romulan ship.

Upon regaining consciousness, they discover they have become invisible and intangible to everyone but each other.

At first, Ro believes they are dead, converted to a ghostlike existence, which awakens a number of Bajoran spiritual beliefs she thought she had abandoned decades earlier.

By invisibly observing the crew of the Romulan vessel, Ro and La Forge soon discover that the accident, as well as the damage to the Romulan ship, is the result of a Romulan weapons test, and that the Romulans are now performing a subtle act of sabotage that will destroy the Enterprise-D the moment that ship accelerates to warp drive.

After discovering and defeating a similarly-cloaked Romulan operative, Ro and La Forge find a way to alert the crew and return to normal, warning Picard and averting disaster.
