Okay, now that I see these 2 together, I can see where these 2 are coming from and how similar they are:Both are very emotional beings,Both have pretty tragic backstories,They both are very dangerous and have done terrible acts,They both control 2 of the most powerful and dangerous elements on Earth,The both had the main character care about them despite being so dangerous,They were both imprisoned a good chunk of their lives until one of the main characters freed them,they both overcame the ones who imprisoned and abused them,their captors/abusers tried to reconcile with them,the list goes on!Madness, you've just made me realise how insanely similar these 2 are and it's a revelation that I'm glad to know.
