For Keeran & the girl, I really like the idea of them being "lost together." And perhaps playing with the themes of communication and comradery without language, and with the ideas of humanity to others.
Armour again! phew. The obvious theme is Magic & Science. But I also like the ideas of mastery in an art or skill, and the ease and "zen" of complete mastery. I can't decide if that fits in my story of Armour, the story with Keeran, or both. We'll see, I guess.
I love you!
