It seemed like nothing happened for a few frightful seconds, the grappling hook was threatening to break under the current...
Just then, it felt like Grisha and Golm hit another current, and they started floating parallel to the Bloodcore. It was still hard to pull themselves in, but at least they are not floating away... yet...
It was hard to see from their perspective when the uruks were floating away from the Bloodcore, but now they can see a single, fleshy robot trying to hang onto the Bloodcore armor as it was nearing where the grappling hook had hit. It seemed to have claw-like feet and four arms.
It got to the grappling hook, grabbed the hook with two arms, and held on to the ship-like flesh armor with the other two. The claw feet sank into the armor as it held the hook down, wrapped the rope around one hand... And then that hand started spinning along the wrist, pulling in the two orcs smoothly.
