Powerful. Very powerful.
My first impression was that if this had been my story, I would have played up Kal's shock at seeing Ching alive, but on second thought your way was better. Kal released his anger and frustration and sense of betrayal on his uncle when he arrested him, and still he was more controlled than I would have been in his place.
You do NOT mess with a man's family where I come from.
You also showed Kal's anger by having him barge into Ti-El's home without taking a platoon of guards along with him. It was uncharacteristic for the careful, cautious, and controlled ruler to behave in this way, but it says volumes about his state of mind. You allowed his actions to speak louder than his words, and it was most effective (and a lesson to me).
Keep it up! I want to see Ching and Zara get together, and of course that would pave the way for Kal and Lois.
