The awesome conclusion to this two-parter. Unlike other issues of this era, this one is referenced in the future as Bizarro + Bizarro Lois became a "thing" in the Silver Age. Bizarro is shown as being misunderstood in his first three appearances, but Superman won't mind if he's dead, which is pretty weird. Supergirl backup story is mind-bending: she comes to the 21st century and basically helps a young boy become Tommy Tomorrow.
