A Series of Unfortunate Evenings
Toph
Toph stood by, helpless, as her friend stood up to Zuko. Unable to see his scar, or his eyes, her mind was forced to imagine what he looked like, and from the description she got, he was ugly and evil-looking. Only Iroh described his nephew as a troubled young man with a good heart, but then, only he had seen beyond the outside.
Now, however, Toph knew Iroh would be disappointed by his nephew. Zuko had not learnt all his lessons, and attacked the Avatar. Toph couldn't tell where he was half the time; most Firebenders tended to avoid staying in the same spot for too long, but it seemed almost ridiculous to the blind Earthbender.
Without mortal eyes, she watched as Zuko could no longer restrain himself, and all his Firebending focused and released a quick blast. The horrible cry of anguish, followed by screams of shock, filled the air. Toph felt the tremor as one of her friends fell. She heard Katara's scream, and was shocked when the water around her flowed, unable to move as one more fell to the ground, killed instead by ice.
A gentle shaking was all that told her it was merely a nightmare. She felt the ground, and found that Iroh was the one who woke her. "Toph, your nightmare might wake the others. They all need rest. Tell me what the problem was." So Toph told him how she had dreamt the death of Sokka and Aang.
AN: Is that plot-twist-y enough for you? Iroh is with the group, and Katara helped kill her own friends… Remember, each story is either a parody, or a horror version of Zutara…
