The Same Blood

OK, this is the first step of my new project, Arno Dorian and his ancestor Yusuf Tazim.

I saw Arno's scar days ago. That scar is so much like Yusuf's, which made me love Arno so much more.
So I had a headcanon: is Yusuf Arno's ancestor? That would be so interesting and sweeeeeeeet!
I know Arno's parents were from France and Austria, but think backward, the wars between Ottoman and Austria lasted for 3 centuries. Anything could happened!
