Re: Resigning from Starfleet
Picard would have most likely put in a word for him, as he was a member of the crew. And if Starfleet had any brains, they would have just put Tarses on a probationary period, and then transferred him into Intelligence so they could place him as a spy on Romulus, continuing the deception.
