Thanks everyone!
I guess I was just confused with the "ndeshou" because... Well, I'm not really sure. I mena, I was aware that it was from the "ndesu" form, just with deshou... Hmm, I dont know, I guess I wasn't thinking, haha.
And to clear things up, my real question was basically asking if "~deshou" can give the feeling of anything else besides something that is probable. I'm pretty sure I've seen it in where I can't understand why it's used, so I was just wondering if there's any other feeling "deshou" gives off.
But thanks again to everyone who helped!
