I'd vote:<br/>(A) Describe the site and the setup procedures, but then skip ahead to the action.<br/>(B) Take the sex scene to a separate thread that can be written in parallel.<br/><br/>Could we meet Ershin's character (Hi Ershin!) on the ground, to explain why she wasn't in the briefing? Maybe an advance scout who was part of the team who picked out the landing site?<br/><br/>
