Johnny Cloud returns to the pages of All American Men of War with a Kanigher and Novick story in issue 115 (May/June 1966).
Running Deer has become a nurse, and is stationed close enough to Cloud that they can carry on a hot romance when he is not off flying missions. They spend some time in a bombed out London in this story. But this is also Running Deer’s final appearance. Considering how long they have cared for each other, despite time and distance, I think that Running Deer likely perished in the blitz of London, rather than the two just parting ways.
But the story is not all romance. Tex gets shot down and wounded. Johnny comes across him as he heads back to base, rescues his friend and kills the invading Nazi.
