Okay so, these are songs I've been listening to. Because it keeps reminding me of Jasper and Lazuli's "relationship" they had and their feelings about it.
Also, I'm a new member so I can't post links. These are just the song names so you can look them up at your leisure. I recommend looking up the lyrics as well so you can make your own opinions
This is an all-female metal band called Conquer/Divide, so, there's occasionally some swears. I just wanted to give a warning (And if they need to be taken down I can do that too). I just seriously feel like a lot of the lyrics are very good at conveying Jasper and Lapis' experience as a fusion, and how they felt during and afterward.
"Sink Your Teeth Into This": Reminds me of how Jasper put confidence in Lapis when she asked her to fuse, but Lazuli used the opportunity to take over and hold her down in the ocean instead. Any trust they could have had has been destroyed.
"Self Destruct": How the both of them felt whilst being stuck in the ocean; Jasper is slowly succumbing to the power of fusion while Lapis battles with her feelings of hatred toward Jasper and the sensation of being fused for so long.
"Nightmares": Both Jasper and Lapis are tormented by their feelings about fusion, and about Malachite. Jasper is aware of the level of aggression Lazuli took out on her, but refuses to back down from her. Lapis tries to convince her that she will only be horrible to her, while Jasper tries to convince Lapis that she needs her. It feels like Jasper is haunting her.
