Can you use Defy on a Bullet Time that paid 2+ power to deal 2+ damage?

Ruling: You cannot Defy a Bullet Time after the opponent has paid power for it. Paying power is part of Bullet Time's effect, and once the power is paid, it is too late to Defy.

Sequence:

• Bullet Time must be Defied before the opponent pays any power
• Once power is paid, Defy can no longer be used
• If Defied before power is paid, the opponent does not need to pay any power
