Honestly, I like Beadsy as a character. He has a mysterious but clearly traumatic background, and an interesting skin color (it’s unclear weather not finishing the Song of the Ancient Stones caused this, or whether he was simply mixed with an unusual snake. Although his human feet are obviously from not finishing the song).
I stand very strongly on my opinion that Beadsy is one and the same as Karl.
Beadsy reminds me of Gollum. He was probably my favorite Fang. He probably was Karl.
