On which subject... Vila really is underused this season. Almost aways on the ship, being lazy and cowardly. Gan's got a stronger role beyond the first three episodes. I can see why, once they'd decided to kill someone in season two, Terry Nation wanted to go for Vila.
I'd never really considered that, I guess because he's my favourite character, and because he's ever present, the initial plan to kill Vila never made any sense, but when you put it like that...
Of course if they'd been making that decision at the end of series 2 I suspect Jenna would have been the prime target!
