They go to another dimension in which the unthinkable is reality: Dan Quayle is President. Walt Simonson’s creativity and originality is wonderful. The only complaint I have about his run so far is this:
Miss Thing has the same exact existential conflict as Ben Grimm when she sees human Ben (she can’t change from rock form, he did) meet with alternate-reality Alicia. This “I’m a rocky monster” storyline is playing out in the exact same way as it has already at least a dozen times before.
