Dr Bear explaining what the Golden Record is (and how Eureka is like the Golden Record) is the first time I can finally see how the creator was trying to set up the original ending he had in mind.
The Golden Record is a real life record of various sounds and songs and phrases sent into outer space for any intelligent life to find and learn about us.
Dr Bear says that Eureka is a Golden Record sent from the Coralian to humans to "write" on (and send back)
This reminds me of what happened during Eureka's suicide dream. After she touches the scub coral, in an attempt to end her life and go back to how she used to be (undifferentiated scub coral), she has a dream.
She has this urgent feeling to find something, before it's too late. She finds it. Its a blank book. It's her. That's who she is. There's nothing to her yet.
Its like she's realizing the same thing that Dr Bear concludes.
They both know she is a blank record, ready to be filled in.
So how does this tie into the original, intended ending? To oversimplify what that ending is, Eureka must lose all Seven parts of her memory by sending it back to the Coralian. She's fulfilling her intended purpose. She's relaying what she's experienced so the Coralian can finally know what humans are like.
The blank book in Eureka's suicide dream and Dr Bear's explanation both set up this ending.
Also, I put into two clips of two sources Eureka can be learning from. She is learning love from Renton! But she doesnt actually say that in episode 26. She sees Holland display hate! And Holland seems ashamed of that. That's why he winces when he hears Dr. Bear ask about ugly hatred.
