1. You guys need to touch more grass, and I don't mean any offense
2. Evil has had chill streams since her existence
3. Vedal doesn't actually see them as daughters (afaik), they are tools/toys/games for entertainment. She doesn't love Neuro more than Evil, but any time he has something in mind it's usually something for Neuro, just because she's the default tool where he throws anything at her, meanwhile with Evil he has to actually think about something that fits her. It's not that he doesn't want her, it's that he doesn't think about her until there is a reason too. He sees no difference between them until a difference is needed, the main reason why he doesn't alternate more between the 2 when he could is probably either for lazyness or because Neuro is the initial brand and it makes less confusing. He doesn't love one and hate the other, he doesn't love either because they aren't her actual living daughters. Mind you, neither Neuro was something he planned from the beginning, her boom just happened. If you really want to know what he thinks about them, then he said multiple times that Evil is more annoying than Neuro, but she has a better voice for singing.
