From what I know, the last we saw of the original team avatar is everyone getting bloodbent by Yakone inside the republic city main hall. I know that Aang recovered and then he chased down yakone and took away his bending. But what about Sokka and Toph? Did they recover?
Originally, LoK was going to be 12 episodes... And this is the only point in the series that the original team avatar is seen. So, like... Is this how the creators were going to kill off Toph and Sokka? That's pretty weak if you ask me, I would imagine Sokka dying by doing something heroic, or stupid... Or dying of a cactus juice overdose at least. I also wanna know what happened to Suki, Ty Lee, Mai and Azula too.
We've never actually seen anyone get killed by bloodbending in the show. We've only seen people immobolized by it. It would be pretty brutal if they actually showed someone getting killed by it. Using bloodbending to stop their heart or shut off all their internal organs... Wouldn't be very kid friendly wouldn't it? So somehow, I find this unlikely. But you never know... I mean, there was the indication that Korra was going to commit suicide after she lost her bending one episode. So I dunno.
