That’s what I intended to get at. They could mention it, but wouldn’t know any special reason they should. And since Boims loves talking about the special ones, but wouldn’t know anything about Discovery. The way the other comment was worded I thought they were just secret in general, which I definitely don’t remember anything like that. I just got confused. I should watch them all close together at some point. Watching in real time week to week with other stuff going on (around season 4 time ahem) make me forget details.
I don’t remember anything about the propulsion being classified. It didn’t come with that, did it? I thought they got that one thing later, after the show was in progress. Was there something special about it when it was built?
