Sergeant Wu is about to find out the truth of what's been going on in Portland in a sneak peek of Grimm.

Snake Monster To Terrorize The Town On 'Grimm'

On Friday, TV Line posted the scene where Wu is behind bars, and Nick and Hank let him out so he can discover something he had no idea about- the fact that all those monsters and evil creatures that he thought just existed in storybooks are actually real. And not only that, but his friends are the ones who stop them.

Wu is extremely hesitant about going with Nick and Hank to see what they want to show him, but there's a huge part of him that wants to know the answers. So he gets in their car as the two guys take Wu to the trailer where all the crime gets sorted out.

Before they head that way though, they stop at a gate where Wu doesn't want to go that much farther. He would rather have Nick and Hank explain what it is they want to show him, but they say that it's easier to show him rather than tell him. This leads into a conversation about the book that Wu found at Nick's house where it turns out that more are around. So Wu obliges and goes with them into the trailer where all the magic happens.

The dramatic scene can be watched here.
