There is a dubbed version of the season on the Internet, though I'm not sure if legal sites have it. Less legal streaming sites, like kissanime, have both the sub and dub.
I have it dubbed on blu-ray.
none, legally right now that I know of, though people have already posted illegal sites in the comments when they aren't supposed to, since it is a ToU violation.
It is legally available on Sony's Platform Crackle.
