Mockingbird surrenders to Dr. Demonicus and his gang along with US Agent. She manages to free Agent who in turn smashes her cuffs. Alas, in the next issue, while Agent gets away, Bobbi, making the sacrifice play to buy him time, gets KO'd and recaptured.

Really nice close-up of Bobbi's bound hands. Those manacles are definitely tight enough to pinch.
