'Agatha... The Covenless Witch' - The Soft Menace in his voice is EVERYTHING. I loved the trailer. I know everyone thinks that Audrey Plaza is the villain, but my theory is that it's actually 'Teen', played by the Amazing Joe Locke (We all know who he really is, but I'll be nice and call him Teen). Like Agatha was manipulating everything in Wandavision, I think 'Teen' the one who will be responsible for 'the bodies piling up', though Agatha will be blamed due to her past. 'Teen' is a relatable 'Villain' though, because he's just desperate to make it to the end of the road and is willing to sacrifice them all for the thing he wants the most.
