There would be a age Gap between them if they do, isn't she like 12 while the prince is near her older sister's age? Like 17-18? She's still too innocent for that ;-; (and suffered a lot)
An age gap like that would be considered normal during a time period like this and 12 was the normal age girls got married at (based on our history).
I’m not saying I agree with the prince and Leslie being married. My precious baby Leslie just needs her new family. Also, if a member of the royal family and the salvatores got married, it would create a huge shift in power for the royals.
The emperor better not make Leslie the new fiancée of the prince ヽ(`Д´)ﾉ
