Steve Guaraldi

Lieutenant commander Steve Guraldi was the chief engineer of the USS Wildfire (NCC-33467) and long term boyfriend of USS Baldwin (NCC-2013) first officer Jaimie Petrelli.

Steve and Jaimie met in 2372 aboard the USS Renegade (NCC-63102). By 2373, they had begun their relationship. During their initial relationship, Steve had fathered a child with Jaimie; however, neither he nor Jaimie discovered this fact until Jaimie discovered their son, Joshua, in 2378.

Eventually, Steve was transferred to the USS Tecumseh (NCC-14934) by 2376, and was later promoted to chief engineer of the USS Wildfire (NCC-33467) by 2378. He would regularly correspond with his counterpart on the USS Baldwin (NCC-2013), Bridget Ingrum, before finally meeting her face to face in May of 2378.

Appearances
Jaimie mentions the fact that she had a boyfriend aboard Tecumseh in the episode "Boats to Build," although his name is not mentioned. He would get a first name in "Mother and Child." In "Family Affair," Steve appears for the first time, and his last name is inferred via his sister.
