I keep hearing people complain that Bolin just just suddenly could Lava Bend & honestly I disagree with them all Bolin had the potential & it wasn't metal bending & Bolin isn't some newb he has training & it would make sense with Lava Bending with Bolin's personality
Also as much I should hate them for being the Villains I love the Red Lotus Group & *spoilers* honestly really sad they are all Dead now (minus Zaheer) :( they were like Team Dark Avatar
Also seeing Korra's past Villains was both Awesome & very Frighting as they all say their very memorable lines that have stayed & haunted Korra in the past Amon & Vaatu sticking out the most as they are very Dark & hit Korra to the Core
& Finally the Ending OMG The Feels! T^T I cried (part of me is really hoping for Korra + Asami ship) but when I saw Korra in that Wheelchair I was in shock (makes me wonder if Nick pulled the show off air cause of these last 2 episodes) & seeing Korra tear up after seeing Jinora becoming the next Airbender Master hit me as much as the ending to Avatar Wan's Story back in Book 2
Here's hoping Book 4 of Korra is just as Amazing as Book 3 was & I hope they don't pull any punches & keep the serious tone that this Book ended on
