OK Breen talks about immortality, and in the beggining, i thought hl2 was about people resisting against breens decrie (spelling?) that no one is allowed to reproduce. Its never mentioned again. Also there is graffiti that has a mother holding a baby and it says resist, another clue that thats what its about. Kinda wierd. The ending is just, so, uggg, its just a bad cliffhanger in my opinion, i think that there should have been a lot of unanswered questions, but simple ones about what you just did should have been answered. Whatever...
