I have a fair number of headscratchers about this game..

[tyranius]

I don't know.. if he sabotaged the elevator himself, he just made things harder for him. Also, (correct me if I'm wrong) Daniel took the amnesia potion because he was almost unable to function knowing what he did to those innocent people. Sabotaging the elevator would take quite a bit of work.. if he wasn't able to function with the guilt, how could he come up with this? And if he was able to sabotage the elevator even with the guilt, why wouldn't he first kill Alexander and THEN take the amnesia potion to wash away the guilt?

I just don't think he'd able to come up with ingenious plans in the state he was before drinking the potion. I believe the only thing he was able to do was write a note to his amnesiac self and that's it.
