It doesn't make any sense that Toph is put in a wooden cell. Reasons -
- It's a Fire Nation town, where the chances that the authorities would round up a Firebender are high, and the Firebender can simply burn their way out of prison.
- Toph didn't reveal in any way that she was an Earthbender, and that too, a Metalbender, a hitherto unknown art which she invented. The then-situation between the Fire Nation and the rest of the world would imply that even if they catch an Earthbender right in the middle of the Fire Nation (the town is Fire Fountain City, a town located on the main Fire Nation islands), they'd send them to higher officials, possibly to the Fire Nation Capital.
Are there any reasons as to which her being put in a wooden cell makes sense?
