I'm glad you guys are enjoying this season, but I do hope the last act of this season hits as hard as it has for the rest of us. I could be way off, but I just feel like this book hasn't impressed you as much as it's been built up for you guys. Maybe not, but I do hope the last act lands for you.
Also we've seen Ghazan lavabending like two different times already π once when he made a lava shuriken to escape prison, and again when they were all fleeing police, and he bent a pool of lava that two cop cars sunk into.
And also a cool bit of foreshadowing in this episode, proof that Bolin could in fact hit P'li in her forehead, was earlier when he was sparring with one of the twins. He couldn't metal bend, so out of panic, he threw a small pebble and it hit him right in the forehead, same place to hurt the third eye for a Combustion bender.
Super excited for the next episode, cause maybe it'll give you that extra oomph that maybe wasn't there. Maybe playing the villains off as mysterious doesn't work well for you guys or it's been drawn out too much for your tastes, but I think that will be remedied soon. See you guys next week!
