I think It's time for a change in the quote. Here are the options:
Look, I get it, you know? You're confused, you can never go back to Homeworld. This place doesn't exactly feel like home yet. You're alone, no one could possibly know how that feels. Oh, wait, I do! We're the same, except...you don't have to be alone.
"It's not a shell. There's so much life, living here. That's what I'm doing! I'm living here! I've been learning new things about myself all the time! Like how I can make metal do my bidding! The point being: Earth can set you free."
