While it is moving a bit slow, that is okay. As for the segregation, I think it is normal, after all we haven't ever done anything to bond with the crew. No life or death expieriences, no depending on eachother yet, to me it is something natural that will be worked out with time. On the subject of rank segregation I think that is something that will be worked on over time, after all when you first meet your Captain you are on your best behavior. I can only imagine that it is the same with most Officers aboard the ship, time as always will fix that of course (unless they are super strict).
As for not posting, in a combination of laziness (sorry), not sure what to post, and uncertainty of whether or not to post (since this part was the sensors crew bit, I'm not worried about getting time in the limelight. Especially since Yoroko sits between PA pilot, Fighter Pilot, and secondary bridge crew). Ultimately I think whatever you decide is good though.
