It's pozz'ble, just pozz'ble, that 'Farscape: The Next Generation' may be coming to the TV Universe. There are rumors that a writer and co-producer of the original series, Justin Monjo, is working on a screenplay for a TV movie that would be about the son of John Crichton and Aeryn Sun. In that time when 'Farscape' has not been on our TV screens nineteen year old D'Argo Sun-Crichton was being raised in hiding on Earth. But his whereabouts would be discovered by the villains of the piece and so he would have to go on the run to reconnect with his parents for their help.
This would be in the near future of the Toobworld timeline. D'Argo was born in 2004, Earth Reckoning, so unless they give him some accelerated alien growth spurt, this will probably be taking place in 2023.
If the rumors are true, this is still just a work in progress and it will be at least a year before it's ready for broadcast.
