YMMV / She Is The One

• Diagnosed by the Audience: Even Jack has no idea what's up with his brain, noting several times that he really should donate it to science when he dies so they can possibly understand why it's so messed up. Jack doesn't appear to have any actual mental illness (aside from accumulating quite a bit more trauma than the average person should), but he is prone to "overthinking," where he dissects and analyzes simple things so they become increasingly convoluted and complicated.
