His portrayal of the self aware hologram Vic on DS9 was always a highlight for me. In the midst of an ongoing war epic, they’d sprinkle in moments for Fontaine to cheer/distract the crew and audience. His beautiful voice helped Nog through the loss of his leg and the PTSD incurred from battle. He got Odo to remove the proverbial stick from his ass. Plus, he helped to orchestrate a ridiculous heist on the holodeck in order to save his program. He will be missed.
Agreed. We got a hint of him late into season 6 with “His Way”
Unfortunately, the only time he and Jadzia interact before the change to Ezri. If only he could have had another full season or more and be akin to the Doctor.
