I think that we have to be considerate. Ken's going through a tough time in his life. For him to take on work might be too stressful for him. As fans, I know we want to support our favorites, but we also have to be considerate and respectful of their privacy. Respect him enough to let him grieve. I don't think any actor can fully work after they've lost a loved one, especially when it's a parent. Noi probably knows what's best for her husband since she's been with him for more than a decade. I don't mind if Ken pulls out for this specific reason because death in a family can truly impact one's ability to focus.
