Another problem with the last few missions, just how do the Reapers manage to sneakily move the Citadel to Earth. This makes no sense for several reasons:

1) It would take time to move it
2) There would be people on the Citadel that would notice something
3) There would be at least one person on the inside who could open it

Edit:
There's a console you have to access to see the endgame messages. Also, I didn't even know you could choose between three endings. The whole "walk towards the colour" thing was never explained to me properly!
