We all know that the crooked man wants to control fabletown. But he dont go out and murder faith and lilly, he has someone else to do it for him. So when bigby fights him, he will probably use a gun like his other goons do. Is the crooked man weak without a gun and without anyone else with him? Idk. Without a gun or anybody with him, he might not stand a chance. But he always has someone else with him! If bigby takes out everybody first and fights the crooked man, then he might bring him to justice!!!
