It's good to hear so many people enjoyed the latest episode. I was a big Who fan as a lad.

On the Borg/Guinan thing... Purely a coincidence, I'm sure, but long before Darth Vader arrived, there was a Who character called the Ice Warrior, a great tall man in armour and a cloak and helmet, with rasping breath, who stomped around giving orders! (1960's) Not to mention The Matrix, a virtual-reality world created by the Timelords, where you could die or heal according to whether or not you accepted the reality. (1970's)

Maybe these ideas just float out into spacetime and get picked up by the big studios...!
