This time John didn't dodge. He raised his forearm to block her hit, circle-blocking and wrapping his arm and hand around her wrist and the poker. So intent on hitting him, but she swung with her eyes closed? A bit of uncertainty and fear maybe. Regardless, he jerked her wrist violently to the side to get rid of the weapon.
Now that he had a hold of her arm he took ownership of it, pulling her closer and then twisting her around abruptly in a fairly simple hold, pinning her wrist to her back and holding the other one at his side so as to keep her from pulling. Unless she wanted to remove it from it's socket. Any motion to move? A small pressure was applied to her wrist, it would be like breaking a toothpick if she decided to jerk or make a move.
Since she didn't want to talk, he would keep her in a hold silently, letting her decide if she'd like to cut the shit.
