More flash than substance: This episode, which was an homage to the movie ‘Inception’, or a direct copycat, looked good but felt like a filler episode. Sherlock got one more clue to Nora’s secret, but he still didn’t expose her. And in the ‘dream-within-a-dream’, Barry and Iris get to visit the Flash museum. Which looked more like a tacky gift-shop than an actual museum.
The one thing we did learn was that innocent little Grace isn’t all that innocent. She’s bitter, because meta-humans killed her parents, plus she’s got a shard of dark matter on the brain. So maybe Grace has got special abilities too. Even though she’s in a coma, she’s aware of what’s going on around her. And Grace is definitely pro-Cicada, sharing his hatred of meta-humans. In her mind, she may even see herself as Cicada.
