Damn what is with the emperor because so far 100% of his lineage has been crazy in some form and they were raised apart! I can't get over how much I love how they are portraying Letio. He's got the perfect yandere thing going, good looking, happy at times with this sinister undertone if you can look past the surface and Selena can. I like that she's taking this seriously, as much as I enjoy yandere, it's annoying when the girl presented to us as supposedly sane herself just bops around with no worries about having a lunatic around. Selena gets why BOTH of them, but especially Letio right now, are going to be huge issues and I can't wait to see how she fends him off.
Also unless she changed him her brother is such a naive squishy boi. No wonder he got done so dirty in the original timeline, and I'm worried that Letio is going to be even worse than Ignius was for him 😬
