"Elsa, your mind, your soul, was transferred into this body you inhabited before you perished. It's why I ensured you're not a 'blank shell' without memory. [A pause] I'm sorry for the loss of your firstborn, Elsa. However, whatever pain you may feel, understand your son lives with me in paradise. An innocent child may never suffer eternal damnation."
A pause.
God answered Elsa's question:
"And as it is appointed unto men once to die, but after this the judgment."
Uh oh. Does that tell you something?
FINAL SCENE:
The scene flickers toward the City of Arendelle once more: It's Summer, the clouds beautifully adorn such a pretty blue, blue sky. The Protestant Movement has grown in Norway, and finally, it's spread to Arendelle. A Christian Pastor visits Elsa from day-to-day, but continually refuses his offer to accept Jesus Christ as her Lord and Savior. This goes on for approximately two years until finally... the old man dies of a stroke.
CUT TO-
Many years later, Elsa is seen worshiping a bright, yellow sun in the sky. Was it bowing? Your traditional psalms and praises toward the sky? Perhaps. We see a familiar symbol hung up on the wall of her castle. There's candles lit in it's honor. The sun: An celestial entity God created to help aid man with heat, sustenance, and life. A mere object.
"I've given you time and time again to accept my son as an atonement for your sins. Elsa, I loved you so much that I left heaven to be beaten for you... to be spat on and cursed... for you... and executed. What more could I have done? You may have been hated and lonely as a youth. But you had me: I would have gladly accepted you as a friend and daughter."
"... But you denied me."
