Sol would live or die as the situation determined; there was nothing more they could do except watch.

He didn't do much except watch, but what he saw overwhelmed him.

"In any event, there's little either of us can do about the situation except watch and listen."

And there was nothing they could do except watch and feel helpless.

There was little enough he could do about that, except watch.

There was nothing she could do about it either, except watch.

There was nothing Herald could do now except watch.

It did bother him, that he couldn't think of anything to do except watch.

Till then, there was nothing more he could do now except watch and wait.

There would be no point in attempting to go to their aid; you couldn't do anything except stand and watch.
