PP 59 is split by other stories, but the break has to happen after Power Pack meets the Circus of Crime (the issue starts with a newspaper article about the circus coming to town) and before Alex starts to mutate into a horse. There is a “soon” caption on the second to last page, but Dr. Power doesn’t appear after that.
