Spoilers:

I chose the blue ending, maybe because I wasn't aware of the full ME story background and importance of indoctrination, maybe because I liked the idea of controlling a vast reaper army to wage war on the universe. I didn't even realize there was a third option.

I'm not sure why so many people question how Anderson gets to the console before Shepard. Clearly he's in much better condition than Shepard at that point (Shepard is bleeding and dragging ass, meanwhile Anderson seems unhurt), so movement would be easier for him.
