"Grimm" is a popular fairy-tale drama that viewers expect to have an ultimately happy ending. However, according to co-creators David Greenwalt and James Kouf, the show cannot start yet its final season as Nick will lose everything and be at the lowest viewers will ever see.

Just recently, NBC has released a new episode title for "Grimm" season 6, episode 4 and it will be called "El Cuegle". This is one of the unusual episodes that you can watch probably in NBC. Aside from that, it is also one of the epic showdowns that viewers will ever imagine.

This next week's episode about "El Cuegle" will feature Renard who will still be around. Aside from that, the episode will introduce a new Wensen and viewers will also expect to see a little bit of unexpected hunting on the part of Eve. She will be trying to figure out certain things which will give her answers about her life, Catermatt reported.

Further, the upcoming episode will feature Nick, Hank and Wu who will have to investigate a terrifying new Wensen who will terrorize a young family. Aside from that, Diana will also have some interesting news for Monroe and Rosalee. Eve will also return to the catacombs in order to search for answers for her bizarre visions and for being healed through mysterious sticks.

The promo for the upcoming season is somewhat short. However, you can expect that it will be pretty terrifying. This will somehow give you an idea on who Wensen is really after for.

On the other hand, Nick and Adalind will reunite together with Kelly on the next episodes. However, Diana may not like the idea of their reunion, Spoilers Guide reported. Viewers somehow don't need to expect the show to fix too many loose ends with Nick's zombie disorder since there will be no enough time for the series to include such.
