Quick! Make a theory that glasses guy's Sigil can be somehow useful, guys!
Power itself is weak? What does it mean? Is it spinning power or it's just depending on the mass of the thing he touches?
If the power depends on the weight of the object, then spinning power itself shouldn't be that weak, especially how he's balancing the pen on the finger, which is impossible for a normal human.
I think the glasses guy isn't thinking out of the box. There has to be a loophole in that.
He said, he spins whatever he touches, right? Is there something else he can use? Pens and balls are spin-able. Is there anything else spin-able?
