Gold's eyes narrow at her suspiciously, too used to being played to be absolutely certain that Regina isn't, well, pulling a him. He's certainly earned that much from her.

He's still debating it, his fingers slowly beginning to loosen from the dagger as he mulls it over, when Zelena speaks up and he almost drops the bloody thing in shock. The fact that he doesn't want to give either of them any kind of satisfaction stays his hand and makes him stubbornly consider backing away.

But...

He remembers the convaluted lengths Zelena went to get the dagger before, the fact that his son died for that thing, the fact that he had to live with all of that when he could have had a satisfactory ending. Can he truly allow all of that to come to pass again when he knows that Zelena's plans will never amount to anything- not in Wonderland.

His jaw sets. Yes, he can.

"No." He lashes out with his dagger, hoping to catch Regina by the wrist, but in his anger and frustration (and possibly some inherent control the other dagger has on him), he misses and only manages to strike the other dagger with a loud metallic clang that sends up a spark of magic that... definitely shouldn't have happened.

What also shouldn't happen is the fact that he can't yank the blade free from the other.
