He can say:
When I would be struck by lightning,
I would be dead.
When you would be struck by lightning,
I would still live.
He can also say:
When I would be struck by lightning,
you would be safe.
When you would be struck by lightning,
you would been dead.
She can say:
When you would struck by lightning,
then I will be sad.
When I would be struck by lightning,
you would been glad.
