German Queen Tomatoes still hanging on

Who would have thought that since all of my tomatoes were just about dead, that my German Queens are making a comeback? What is that all about? I pulled off a tomato hornworm last week from the German Queen. Half of each plant has died off, I believe from so much rain that they just about drowned, like my other tomatoes. But now I see healthy growth. I see more blossoms! I see tomatoes growing! I know it's bound to be a cruel trick. One day soon it will frost over, and then they'll be gone. Crazy weather we are having. And crazy tomatoes!
