'Teen Wolf' Season 5 Spoilers: What Is Parrish? Ryan Kelley Knows The Truth, Do You?

The Dread Doctor's werewolf puppet will do just that, however, and he will do so by backhanding Lydia's (Holland Roden) face the midseason finale.

You've really crossed a line Mr. Raeken (Cody Christian).

'Teen Wolf' Season 5 Spoilers: 'Insane' Finale Coming, Are Scott & Stiles Really Through?

The attack will come moments after Lydia's banshee powers clue her in to another death in the library. Unfortunately it won't be caused by Colonel Mustered with the lead pipe. Instead, Lydia will hear snippets of Scott (Tyler Posey) and Liam's (Dylan Sprayberry) battle, but the teen's prognostications won't tell her which - if any - of her friends will take the fall.

Liam, however, won't want Lydia leaking even a little bit of info about the Alpha/Beta showdown. Instead, he will take Lydia down in an effort to take Scott out of the equation for good.

Check out the preview below and tell us what you think will happen in "Status Asthmaticus."
