Timothy (Lieutenant)

From Memory Alpha, the free Star Trek reference.

Timothy was a 23rd century Starfleet officer specialized in the operations division. He graduated with James T. Kirk from Starfleet Academy and was a mutual friend of Kirk and Ben Finney. Timothy and Kirk served together during the Vulcanian expedition, they would not see each other again for some time after that.

In 2267, while on a layover at Starbase 11, Timothy confronted Kirk following the apparent death of Finney, blaming Kirk for killing his friend. He was at the time, sharing a drink at the bar with his friend Mike. (TOS: "Court Martial")

Timothy was played by Winston DeLugo. Although not explicitly stated on screen, Timothy may have served aboard the USS Republic along with Kirk and Finney.
