The tell might be the fact they trust her and also a few things of how they view power and villainous tendencies

On the fence about SS. Seems like a familiar who’s named after her son for sentimental reasons. I *think* the tell is chaos, likely magick derived from Chthon. Think of how messy Billy’s whole journey is, much like Wanda’s powers functioned for a while in the pre-Wandavision MCU.

Good point on the bunny. He is oddly and obviously present and so far nothing was shown without a reason.

I had seen on New Rockstars a theory that Tommy’s soul went into Senor Scratchy

sene this somewhere: “ In an interview, Matt Shakman said that a scene was filmed in which Señor Scratchy would have turned into a demonic figure. The scene was not used in The Series Finale because it was considered "a huge detour in the middle of everything" that was happening in the episode, and the VFX was never finished for the scene. “ but idk if they’ll stick to that
