Yeah, but what does Second do that allows him to work with the tangle?

Second's ability is to manipulate the Strings of Fate. Everything in the world that interacts is connected with a series of string-like paths. When I walk forward, I'm following one of these paths. When some beings use their abilities, though not all, they use these paths to interact with whatever it is they're doing. Even gravity has its own strings that pull all of us toward the ground. Likewise, this enemy's ability entangled us with its own strings, so he had to untie those like a big knot.
