Glen and Frank in “Wide Open”

'John Allworth.' The signature... centrifugal, vertical lines, forward expansion. The strokes... forceful, measured, alternating cursive and print. This man's signature's probably been the same since he was old enough to sign it.

What does that tell you?

That the signer is deliberate. He has focus, but that this is to contain his rage or his anger -- that he can be explosive, prone to outburst or violence.
