Coming up alongside the CMO, Vanya noted the woman's subtle show of discomfort. "Would you like something for that?" Generally Enzo was the one to pick up on issues faster - one of the 'perks' - of being Betazoid, though he didn't make overt use of the ability outside of direct necessity. For her part, though, Vanya prided herself on powers of observation, and from what she'd seen of Dr. Darney, the woman was not one to give outward evidence of pain unless it was jumping on the threshold.
The Dyson Hive
Synopsis: The meeting with the Klak'kati hive went well, at first, but the crew of the Hiroshima soon learned that they had been, in fact, herded (see Ice Capades synopsis) by the Breen, who'd placed a cloaked pod on one of the ship's nacelle struts. This pod replicated and distributed a lethal virus and the Hiroshima was its unwilling (and unknowning) host.
Initially blamed for the outbreak, the crew of the Hiroshima successfully navigates a touchy diplomatic challenge and, while the Klak'kati Hive is closed (for the time being) to the Federation, it is not an enemy.
