How we cite our quotes:
Quote #1
"The Bible speaks of the Ark leveling mountains and laying waste to entire regions."
If we're talking big changes, then the Ark is clearly the tool to do it. Nothing like the power of creation to get rid of that pesky mountain range lying in your path.
Quote #2
"Think she'll still be with him?"
Indy's relationship with Marion is a key part of the story; namely, his jerk-boyfriend behavior and the ways he learns to turn it around. Here, we see that she's still on his mind, suggesting that maybe the big lug feels awfully bad about what he did.
Quote #3
"I was a child! I was in love! It was wrong and you knew it! You knew what you were doing. Now I do. This is my place. Get out!"
Marion's older and wiser. Indy's older, but not so much wiser yet. Feeling bad about your mistakes isn't the same as making them better, which takes more time and usually involves more groveling. The groveling process begins here with Marion venting all the bile she can muster at him. Even so, at least they're talking, which suggests that the necessary healing has begun.
