Season four got off to a great start last week and the fun continues with the episode "Octopus Head" on an all-new Grimm tonight on NBC. Last week's Wesen had to be one of the most gruesome on the series so far, with the Gedachtnis Esser using his head tentacles to literally delve into someone's mind and suck their memories away! His victims were left with no memories of their entire life when he was done with them. So brutal! The creature, Lawrence, is still on the loose. Most fans of the series are probably thinking the worst part of the episode was Captain Sean Renard flat-lining at the end though. Gasp!
In tonight's episode, "Octopus Head," as Nick and Hank turn their attention to a string of attacks where victims are left without their memories, Nick weighs whether or not he should regain his Grimm abilities. Trubel joins the investigation and puts herself in harms way. In Vienna, Adalind is being held captive and learns that she is more connected than ever to Nick. Meanwhile, Captain Renard continues to fight for his life as a mysterious visitor arrives to help him.
