They're still making audio stories. Jan Chapel did a Cally Prequel I saw advertised on a website recently. So they could pull any coloured rabbit out of there hat just to freak with us out and jostle the status quo.
Here's a detrimental thought, the way Avon said "Cally's dead!" was almost exactly the same tone as Blake used when he said "Gan's dead!" and honestly, if Avon reacts the same when his lover dies as Blake does when Gan dies, does that mean that Blake and Gan were lovers?
If he was gay however, however unlikely, that would have been a fantastic defence at his trial for paedophilia in the pilot: "I'm sorry but if I was going to sexually abuse children, it wouldn't be "that" gender."
I dunno, he seemed awful fond of Jenna (then again who wouldn't be!)
We used to have a dog named Jenna and dad never said where he came up with the name.
Then one day when some-one met her, he commented "you're a Blake's 7 fan too?".
So Jenna Stanis could well of been the inspiration for the name though I had no recollection of seeing the first couple of seasons.
