Ahsoka was 14 when she was first introduced but she was 17 when she left the temple which is age of consent in most countries including the US. Also, romance feelings can be developed before anything can be acted on which means a time skip could also be shown as a before and after the budding emotions. I don't plan on writing for her or against her below that age if anything sexual were to come of it so I don't really need a warning for that.
Were you wanting to write, or just discuss her age?
