A friend of mine has recently started watching Legend of Korra, however they've just explained to me how, for very personal reasons, they aren't comfortable watching the effects of bloodbending.
I have a very hazy memory of the first season of LoK, and past that I didn't watch it.
Is there a list of episodes that include bloodbending available, and possibly timestamps? If possible without spoilers.
This should help them either avoid or at least prepare for when bloodbending is shown on screen.
