Ensign Rainer was a Starfleet tactical officer serving aboard the USS Enterprise-D in 2370.
He was assigned to the night watch and was on duty while Doctor Beverly Crusher substituted for Lieutenant Commander Data, who was retrieving fragments from a crashed Federation deep space probe on the planet Barkon IV. Rainer attempted to hail Data and inform him of a delay in the planned rendezvous with the Enterprise-D, but was unable to contact him. When he informed Crusher of this, she ordered him to continue updating Data on their schedule. (TNG: "Thine Own Self")
Rainer was played by Richard Ortega-Miro.
