no-one has to die.

"no-one has to die" except the two security guards that nobody seems to care about

The security codes arranged in a square grid say 'Rise from the ashes'!

In the last timeline when the visitor says "Hey, has anyone unlocked the door for me" there is a pause. I was absolutely expecting that it was going to say "Calculations complete. Fire on floor 1. One casualty unavoidable. Candidates: Visitor"

So that's why the phrase was: Christina lives. If they manage to find the bird it proves that Christina's mother Christina is still alive. And I had to read back to understand what Lionel meant when he said they were looking for a phoenix in the cockateils. Crazy reference to the characters dying in a fire. It's a very well thought-out game. The puzzles were simple, but it's very hard to design a puzzle that would work with all the different storylines with the same layout, considering the buildings they were in and stuff. So maybe that's why they had to keep it simple, and the main thing was the story anyway =)

I think my mind exploded. Or maybe it went to the past. Or future. I have no idea, honestly.
