The Ending? **SPOILER AWAIT...**

[GunbladeMaster]

um ok so
what happened in the ending?

why did Ramza and Alma run away from society?
and whats up with the "after the credits ending"

Ovelia stabs Deltia and the he stabs her back right?
Why did she do it?
I know she said:
"You are going to use me than kill me just like everyone else!"

Where did she get that idea from?
But then she dies right and he says

"Ramza...."
"What did you get..."
"I............"

and then its over
can someone care to explain this to me?
most appreciated
