Karin and Fuinjutsu

From the many theories on here, and from what we know, the Uzumaki clan was extremely powerful and were feared by many people. The clan was known for it's sealing capabilities, but it was killed off. They're aren't really any other Uzumakis around that we know of, since Nagato died. Naruto is an Uzumaki, but he's kind of a half-blood. Kushina and Mito were both exceptional at sealing techniques, but that was because they were alive when their clan was still around. Karin didn't even know she was Uzumaki, from what Orochimaru says, so I doubt she knows any Fuinjutu., but I'd love for her to do something that relates back to her clan. Something Fuinjutus-like that can help with the war. I used to think the chances of Karin doing something Uzumaki related were slim to none, but with everything that's going on, there's a bigger chance now that Karin could play a role in the war with something that relates back to her heritage; I hope so at least.
