Now that the fandom has exhausted the 'Rose Quartz is Pink Diamond' and 'What the heck is Bismuth/that gem in Lion's mane?', it's time for everyone to join the bandwagon and speculate about who/what Lion is and who Pearl belonged to. Hey, what are Steven Bombs for if not to cultivate new theories?
However, please do take a look at the video below, as it does actually add new and frankly interesting evidence as to what Lion might be. It's a new spin on the theory that I haven't seen before, so it's not quite the same old same old that a lot of theorists merely repeat.
