Oh, what a tangled web. You have Madelyne, who thinks that she knows Alex. She hears his voice through her headphones every night. They share inside jokes and memories of times spent in a virtual world. He listens. He understands. He is everything she has been looking for - and suddenly she has a way to be Em to his Lex.
This song makes me think of several scenes - Em, upon arriving in Tyrael and seeing it for the first time, then Em outside the cabin, looking up at the sky. Em receiving her tattoo. Em trying to separate Lex from Alex. "I'm gonna get you out of here/if I could catapult my heart to where you are."
