So I have seen Spectre twice now and I'm confused about one thing.
When 007 gives Q the ring he puts it on his magical scanner thingie and his laptop eventually pops up with "DNA Match" (or something along those lines). The program he is running then promptly puts it into a nice graphic with the faces of all the villains with lines connected the baddies to each other (Also inside an octopus shape... lol).
My question is how is the DNA found on the ring meant to match the 8-ish bad guys? My current running theory is that maybe the ink in the ring matched some rare octopus or something. Did I miss an explanation for this in the movie?
