The origin of the boy
At the beginning of the game, when you are fleeing Earth, you can see the child you will eventually talk to running away from Husks. Before you get to the part where you see Husks climbing up the wall (the first time you shoot at something), you can see the boy looking below, looking over the railing. When the Husks arrive and Anderson coaxes you to shoot them, continue to observe the boy run into the building and lock the door. The building is blown up seconds later, but he apparently survives in the vent.
Passing out in Purgatory
When in Purgatory, go to the bar and have a drink. Then, have another one and one more after that (three total without leaving). You will pass out and wake up moments later, in Purgatory.
The Hunt For Red October reference
During the introduction sequence for the mission where you are about to land on Rannoch, Commander Shepard is standing in the Normandy's bridge talking to Joker about the fact that there sure a lot of enemies out there. Joker laughs it off and says that with the Normandy's stealth drive engaged, the only way for the Geth to notice you is if you all start singing the Russian national anthem. This is a direct reference to the 1990 film, The Hunt For Red October.
