A young ensign in engineering on the Enterprise-D in 2370 who is plainly taken with Geordi La Forge while the crew struggle to start a new warp core.
Ensign Tyler serves in the engineering section of the USS Enterprise-D. She appears in the episode Phantasms, played by Gina Ravarra.
The ship has been fitted with a new warp core that will not work properly, and La Forge is under pressure to put it right. Tyler keeps finding reasons to be near him. She offers help and brings him things he has not asked for. La Forge sees what is going on and does not know how to deal with it. He ends up asking Data for advice.
The lighter story runs beside Data's troubling dreams, which lead him to stab Counsellor Troi. Those dreams prove to be warnings about unseen creatures feeding on the crew, and the same creatures are why the engines failed. At the end Tyler is still looking hopefully at her chief.
