Synopsis for "Those Who Change"
A human colleague warns his friends to give up their dangerous time travel experiments lest they alter the entirety of recorded history. He leaves, and the two scientists scoff at his warning since they are unshaken in their belief that the past cannot be changed. They send a camera back to the earliest beginnings of life where it bonks a creature on the head that was just beginning to emerge from a tide pool knocking it back into the water. When they recover the camera in their present and examine its records, they state, "The professor was wrong! Nothing has changed! We knew that the present could never be affected by what happens in the past! And we were right, as usual!" (The last panel shows the two scientists are now reptilian creatures.)

A circus owner's daughter is friends with a tightrope walker who's past his prime, but can't accept it. He continually asks the owner if he can take to the act just one last time, but the owner refuses because of his advanced age. When the regular tightrope walker doesn't make his show, he realizes this is his chance to get back into the spotlight and begs the owner to let him go out. He agrees, but the man's body fails him during the act and he falls into the net. The audience boos him, but the owner's daughter thinks it's all part of the show. She takes seriously ill with fever that hospitalizes her and calls out for the tightrope walker. The owner is astonished when he appears. They move her bed to the window overlooking two trees where the man suspends a wire and commences to perform the best show he's ever done. When the girl's fever breaks, the grateful doctor looks back to the window to discover the tightrope walker is gone, and the owner reveals that because of the injury sustained in his fall the tightrope walker died in his bed an hour earlier.
