Watched "Rat King" from Grimm. Three young men torment and kill a rat-like Wesen boy, but two are attacked by the Rat King, a 20-foot-tall Wesen that comes into being when a group of rat Wesen assemble themselves and become as one. Nick, Hank, Monroe, and Rosalee trace the Rat King's hideout to a junk yard, where the Rat King is (are) subjected to electric shocks when Nick instructs Hank to shoot a power line.

Nick takes Adalind to hospital, where a group of hospital staff embers, apparently anti-Grimm, connive to take Trubel to ICU to undergo "brain surgery". Meisner visits Adalind in the nick of time (pun intended) and asks Nick on the phone where Trubel is. Nick and Meisner rush to the hospital and are able to overcome the hospital staff members.

Nick takes Trubel to his residence. He then confronts Adalind and demands to know who Meisner is.
