This week, we get a Peek-a-boo at a new rogue, a glimpse into Barry and Caitlin’s personal lives, a role for Barry’s father, a set-up for Firestorm’s reappearance, and a teaser for the most-anticipated Flash villain’s debut.

If that big hairy deal at the conclusion may be the High Point (though it was a decent episode overall), the Low Point continues to be the constant reminders that S.T.A.R.’s prison (apart from being illegal) is practically unworkable.
