: This is easily one of the best written and most interesting terminals in the
: game. And yes, it is the Joshua. It seems almost out of place with the
: rest of the game due to the fact we never really see any like it again.
: All most all the terminals are up-to-date.
I don't think it's exactly an alias- I think the entity we call Joshua infected Science Office Joshua Rillings like John Carpenter's Thing, then used his identity to subvert the ship. He would then answer to that name for the rest of the scenario out of convenience or habit. It's possible that the "real" Joshua never had a name before taking over the science officer. This was actually the first time I noticed that tidbit, so we'll have to be careful to watch for a similar "origin" for Michael, since I don't remember anything like that for him off the top of my head.
