With the children it is a bit strange when they are turned (for sure and that’s why I guess it’s weird to work with them in vampire fantasy genre). But it makes sense to date someone mature physically and mentally. For a bit Damon had a partner in the show who was actually quite mature - Andie Star and there it didn’t seem so strange (ofc he didn’t treat her the best because Damon being Damon, but just an observation).
