^I assume a blue haired girl and a silver haired boy?
Mmm as for the 'What If...' (at your request):
Meg: Hi.
Leonardo: Hello Meg.
Meg: What you doing?
Leonardo: Well, I'm repairing my bow's string right now. This thing is about to break. Could you give me a hand?
Meg: Sure! What should I do?
Leonardo: Mmm, take my bow, please. Now, just passing this around here...then this...done. Thanks, Meg.
Meg: Why don't you try it?
Leonardo:...There. Pretty cool and excellent.
Meg: Wow, you fired it way too far! Amazing! You could hunt easily like this!
Leonardo: Thanks Meg, see you later.
Meg:...Father, I'm sorry, but I'think I've fallen in love with someone else.
What if Nergal remembered that Ninian and Nils are his children?
