Lion 2: the Movie is the second episode of Steven Universe to be about Lion. It's about Connie telling Steven about this new movie. Steven then tried to get Lion to take them to see it. Lion ended up taking them to something about Steven's mother's past. These Lion episodes tend to do stuff about Rose Quartz's history. Though not everything about her is covered in the Lion episodes. Rose Quartz is a big character in Steven Universe though we don't see her in the current day due to her having to give up her physical form to give birth to Steven. She's the person to blame most to all Steven's problems throughout the series. This episode may cover her more indirectly as it's about a place that used to be hers that's confirmed more in a later episode. Steven Universe is a deep show with deep lore and this shows it does try to show it earlier on. Steven Universe is a show I really grew up on and helped shape my opinions on stuff today.
