Fletcher (Ensign)

From Memory Alpha, the free Star Trek reference.

Ensign Fletcher was an engineer serving aboard the USS Enterprise-D in the mid-24th century.

Fletcher was already aboard the ship on its maiden voyage to Farpoint Station in 2364 and among the crewmembers who welcomed Captain Jean-Luc Picard on board in the cargo bay. In the anti-time past, Fletcher was supposed to get Lee and Munoz down to main engineering to realign the power grid. (TNG: "All Good Things...")

When Geordi La Forge suddenly felt dizzy due to a temporal anomaly distorting his VISOR in 2368, Fletcher was able to grab him before he could fall down from the catwalk to the bottom of the warp core. (TNG: "Cause and Effect")

In 2370, he was considered for a higher position in engineering as he was experienced in propulsion systems, but his colleague Carstairs was preferred by Counselor Troi and Commander Riker as she was better with people than Fletcher. (TNG: "Lower Decks")

Fletcher was played by an unknown actor in "All Good Things...".
