Why is it that Amon and Tarrlok look like their dad's new face, rather than the face he had before the surgery?
Also, I'm still confused whether Amon was getting revenge for his dad, or actually going for equality. I mean, he got kicked out from a window, fell in the water, his "scar" disappears, and everyone notices that he's a water bender... Then he runs away and practically says, "Eh. I give up. C'mon, Tarrlok! Let's go boating!" Honestly, I think he was just trying to get a wack at the Avatar, because it really didn't seem like he was out for revenge in the first place, either. "Oh, I took away a lot of my fellow bender's bending so I can fight you, Avatar!" Couldn't he just ask for a duel? The more I think about this, the more stupid his motive sounds. I don't like it. I don't like his motives. I don't think I'll be able to re watch Korra the same way I did before.
EDIT: And another thing! If Amon really did believe in equality, like they said he moderately did, why was he acting like a total punk to Tarrlock when they were young. Why did he even continue blood bending, knowing that it hurts people? Tarrlock blatantly said it, yet after leaving the water tribe, Amon continued to blood bend. NO SENSE!
