In a situation where you are not only Mounted, but also, your legs are grapevined, and you try to Trap and Roll them, but their arm is too stiff, you can do an Elbow Escape, and put them into your Guard.
But first! You must remove their grapevined hooks around your legs. To get rid of the first one, simply lift your leg up and to the outward angle. Then take that freed leg, with the foot, push the foot of your attacker's other leg downward to the ground to free your other leg.
From there, you do the standard Elbow Escape.
