Sorry to Necro such an old thread, but I managed to get the S2 Bonus Disc and all its special features.
Someone on Reddit bought the disc and uploaded it to Archive.org. I grabbed it when I could but I don’t think it’s still up there. If anyone is interested, I can reupload it.
The Season 1 disc is still missing, so if anyone is able to find that too, it would make a great match.
