The Flash Season 6 Review: 7 Ups & 2 Downs From 'Grodd Friended Me'
4. Meet Mirror Master 2.0.
Ever since Eva McCulloch debuted on our screens, we wondered if and when she'd become the show's next villain, the reason being that she's a gender-swapped version of Evan McCulloch - a.k.a. the second Mirror Master.
Though the sheepish genius initially proved to be more ally than enemy, things took a dark turn when the closing moments of this week's installment revealed that she wasn't just not who she appeared to be, but that she was controlling the dark Iris living in the real world - and together, they're clearly planning on doing something with that Mirror Gun.
Whatever that is remains to be seen, but the fact of the matter is that Eva McCulloch's heel turn was so well-hidden in plain sight that we'd begun to suspect that she wasn't the villain after all. But Efrat Dor's already looking like a potentially great Big Bad after only scene, so it's safe to say that this writer is excited to see what she does next.
