Brooks mentions that were legends, but Shepard doesn't mention the other crewmembers and the ME2 squadmates as legends, which they are, for helping defeat the collectors.
Just before you jump across and the destroyer fires at you, you hear Mordin saying he's preparing the cure, and since I have T'soni, she says by the goddess, to our left. What I did was go back from where I came from to see if I missed anything. I didn't. I went back to jump, when Mordin and T'soni say the same dialogue again.
After the Turian fighters shoot at the destroyer and before you jump down to face the brutes, if you stay in that spot for what semed like longer than 30 seconds, a critical mission failure screen comes up.
After killing all the brutes, if you choose to, as you move towards one of the hammers, look up and you see the destroyer with its leg up in the air ready to stomp on you when you move. Its funny if you don't move and it has its leg just up in air like that. Too bad I didn't have a stick and throw it to see if the destroyer wanted to play fetch
After the 2nd dream, I usually pick the bottom right dialogue to end the conversation quicker with T'soni, but this time I chose the upper right dialogue with femshep saying she's thinking of Kaidan. Liara mentions Kaidan and in my playthrough from ME1, she never met him.
When Addams mention needing a thermal pipe, Ken turns his head to his right making some comment instead of turning his head to his left where Shepard and Adams are standing.
