The saddest scene in the entire show

Want to know a fact that makes this scene more heartbreaking? Amon has the ability to detect movements due to his blood bending. That’s how he could dodge attacks. Anyways, he felt his brother put on the glove and open the gas tank. He cried knowing his brother was going to kill them both

This scene was a somber moment, because Tarlok realized him and Amon/Noatak became what their father wanted them to be, so he put a stop to it before anyone else got hurt.

Amon knew exactly what Tarlock was doing and didn't stop him because he wanted to die. That's why he shed that last tear.

I like how we’re all collectively going through an Avatar phase again

Tarlock closed his eyes because he couldn’t see a path ahead for them. Noatok kept his open because he could see the end of it.

Their father committed crimes, escaped to a new place with a new identity and passed the hate and quest for vengeance to his offspring. They committed crimes and were escaping to a new place potentially starting the cycle all over again but Tarrlok put an end to it. Kind of poetic.

The fact that Noatak probably feels Tarrlok grabing the glove knowing he'll die and doesn't do anything about it speak for itself.

I’ll admit that LOK wasn’t my favorite, but this was a brilliant scene. There’s just something indescribable about it that makes it seem perfect.

Noatok definitely felt what his brother was doing. He didn't bother to stop him because he knew what he had done and didn't want to live with the guilt.

This was a very shocking and impressive season ending. Even though they were villains I was saddened by the route they chose. Very strong and unique characters both

For me this scene had such a huge impact, because at that point after losing his bending and all ambitions, Tarrlok felt like he was a no one anymore. So, this could possibly be interpreted as "I have nothing left" from Noatak's words. At the last second, he sheds a tear of final remorse, as he realized that he was going to die, he could have easily bloodbent Tarrlok's hand away, but didn't try to stop his brother, because he knew there was no bright future awaiting. Both siblings had nothing else to live for, thus making up the decision to commit sudoku.

I swear. This is the most heart-breaking, gut-turning, and life-changing scene I had ever seen in my life.

Depicting suicide in a children's show was a pretty brave decision.

Even as a child, I knew what that tear meant.

The saddest thing is them knowing they became the thing they swore to destroy, tools for Yakone’s own legacy
