Was Vader just messing with Jejerrod, or did he not know how far along DS2 was?
At the start of Jedi, Vader makes a big deal to Jejerrod of the Emperor being "most displeased" at the "lack" of progress on the second Death Star. So much so that he's doing a site visit himself.
Jejerrod is visibly terrified. But was Vader just trolling, or did Vader genuinely not know that the station was close to, or had an operational super laser?
It also begs the question, as we find out later, the Emperor visits to draw the rebels into a trap, so did Jejerrod also not know this plan?
