Dr. Benjamin Kyle was Babylon 5's original Chief Medical Officer having been loaned out by Earthdome from his post as head of Xenobiological Research. Stephen Franklin replaced him on March 2, 2258. He performed surgery on Vorlon ambassador Kosh Naranek after the ambassador was critically injured in an assassination attempt, making him the only known human at that time to lay eyes on a Vorlon. He subsequently visited Lieutenant Commander Laurel Takashima to enlist her assistance in persuading a commercial telepath, Lyta Alexander, to perform an illegal telepathic scan on Ambassador Kosh. Takashima agreed to Kyle's proposal and proceeded to convince Alexander to go ahead with the scan. Bound by his oath of confidentiality, he never told anyone what he saw.
