Question about the story

[alr343]

Hello

I missed some things about the story at the beginning and now I'm all confused.
I just have 3 quick questions.

How did the very first Simon copy got into the facility? (Who transfered that copy into the facility)
How did Simon get the water-type suit after he is unconcious?

The last one is...

What happens if you don't kill your past body in Omicron?.
Will he regain conscious and go insane? or will he die eventually?.

Thanks!
