Thank you to @omniscientnpc for this idea
When Petra is told Romeo can't remove the curse anymore, she almost gives up, ready to believe Jesse may be lost to the curse permanently, but Romeo has an idea. Though he designed the gauntlets to be hard to break, it's not impossible, Jack supports this as he remembers breaking his gauntlet long ago but it nearly took him over in the process, Nurm is probably the one who helped him
Though the gauntlets are hard to break, using its power, especially now that Romeo is human, could eventually lead to it breaking, which theoretically is what Jesse is attempting to do, but it is also much easier and much faster to do so with something of equal power. Something like another gauntlet. Petra realizes one of her fears, she has to fight Jesse, one of her closest friends, if it means breaking the curse once and for all.
So Petra leaves her hiding spot and calls out to Jesse, grabbing his attention. The fight begins.
It's a fierce battle, Jesse's rage-fueled attacks sometimes make him unpredictable, but Petra is able to hold her own. Much like the golden gauntlet, it takes a few hits, she can hear Jesse scream underneath the armor whenever his gauntlet is damaged. Eventually, the final blow is made, Jesse's statue form shrieks as he falls onto his back, the gauntlet is broken, and without it, the statue becomes still and quiet on the floor, inactive, it isn't long before the armor poofs out of existence, revealing Jesse, now freed.
At the same time, Petra's netherrack armor breaks, her gauntlet also destroyed in the final blow. Ignoring this, she runs to Jesse, everyone else following her as Jesse opens his still glowing eyes. He gets a look at his hand, no longer stuck in a cursed gauntlet. After moving his sore arms more, testing if he can move on his own, he laughs a little, grateful to be freed, but the realization hits him once he sees Lukas. He attacked people, he attacked his friends. It's possible that he may have even killed someone. Jesse apologizes, saying that he couldn't control himself. Petra stops his words, pulling her friend into a hug. "It's not your fault." Petra tells him.
Lukas joins in the hug too. They both know what it's like to not be in control. As Jack and Radar also join the hug, Jesse returns it, breaking down into sobs.
Romeo, meanwhile, stands aside, this reunion is for Jesse and his friends. And it was his fault Jesse was even cursed. If anything, he doesn't even deserve to be alive to witness this event.
Yes, the gauntlet must be hit directly
