I forgot to go back and save her in episode 3. I wonder if something special happens for saving her in every episode or if its just a running joke to keep saving her from getting hit all the time
She has some extra dialogue option including a quote that may or may not be relevant foreshadowing. Haven't seen it discussed either. It's by Robert Frost.
"I shall be telling this with a sigh
Somewhere ages and ages hence:
Two roads diverged in a wood, and I
I took the one less traveled by,
And that has made all the difference."
No idea what this refers to - finding the extra graffitis when going off-path in the junkyard at the end there of Ep. 4 there, or if it refers to the percentage of people that chose something, or if it's hinting at a reward for doing the extra most don't like helping her all five times (she does mention you helping her all the time reminds her of that quote, so...)
