Spencer: A mystery story cannot work with only one suspect. Without false leads and red herrings, everything’s too easy; we know whodunit before the story’s even begun. In Flash 21, Kid Flash becomes one of those false leads; the problem is, Barry is the only one actually trying to solve a mystery here. Us readers already know that the Reverse-Flash is behind these murders, leaving the real bulk of this issue to be carried by the first meeting of Flash and Kid Flash. I’m not sure the two of them are up to the task.
