I heard McFarlane confirm that McDonald had recorded all his lines for this season before he passed.It looks like they finished shooting this season last August and Norm passed away in September.
Lots of Starship Porn in this episode.
Also, was I the only one who thought that it was incredibly reckless for them to be holding the Pteradon's combat test in the middle of the Orbital Shipyard?
That said, I agree that this episode took a dark turn with Isaac committing suicide.
Not sure what role Burke is supposed to filing her though, even if Anne Winters is now a series regular.
