I believe saddestmoon meant that the red Excelsior is not on the screen in Marcus's office, rather than not in that scene.
Thanks Praetor and Andymator
Yep - that's what I was referring to.
Gerbil - The red-hulled ship is shown onscreen (as I mentioned earlier in this thread, and in the thread I started a little while back, discussing the onscreen appearance of the mysterious red hulled starship - http://www.trekbbs.com/showthread.php?t=213985
), but it is not listed / shown on the Spacedock Manifest (on Marcus's display) - which is why I then went on to suggest that it might have arrived at the dock after the Marcus Office scene (hence why it didn't appear on the manifest).
Hope that clarifies things.
