In the latest promo of “Teen Wolf” season 6 episode 7, Liam asks Scott whether he trusts Liam or not. Scott replies that he does not trusts Theo. Liam tries to explain, “I think we can use him.” Scott reminds him how Theo got into Liam’s head and persuaded him to kill Scott.

Both of them are trying to find out Stiles (Dylan O'Brien) but the confusion of whether or not Theo will prove to be trustworthy still prevails in their minds. Liam further talks about how they need to try everything to find Stiles, even Theo. The clip ends with Scott saying, “Convince me.”

In the last episode, the Sheriff (Linden Ashby) was seen looking at the torn wallpaper in the Stilinski household.
