The hype of the “Rat King” episode had me quite excited but unfortunately, I’m left wanting. “Rat King” has its moments of intriguing plot points but overall, it is a lackluster episode. I am, however, happy to see Trubel (Jacqueline Toboni) again, even though she is completely battered and bruised. Where has she been and what the hell has she been up to while she’s been gone?
