In the "how did I miss this" category for the Mass Effect games...

So in Mass Effect 3, one of the quarians seen in the Tron ripoff mission... I mean "Geth Fighter Squadrons," of course, right...  Anyway this quarian's name is Hala'Dama.  If I must explain the joke, this is the part of the game where you learn about how the quarians created artificial intelligences (Hal) and were then driven from their homeworld (Adama). 

Other random thing that I just want to comment on all the way back from the original Mass Effect: at the end of the Virmire mission, there's a music piece called "Exit." The first part of it plays right when you have to choose whether to save Ashley or Kaidan. The very beginning of that piece starting at the 13-second mark is a sped-up version of the love theme, the first time you hear it in the game. Obviously due to the gameplay mechanics, they weren't going to have the love theme running in pre-Virmire (hell, pre-Ilos) conversations with your love interest, but it helps make this situation unique.
