That which is the same at the end of the first [week] is washed and confined. That which is the same at the end of the second [week] is burnt. That which expands [at the end of] either week is burnt. [If] it turned dull during the initial [inspection], R’ Yishmael says: It is washed and then confined. The Sages say: He does not need to. [If] it turned dull after the first [week], it is washed and confined. [If] it turned dull after the second [week], he tears it out and burns what he tore — and it requires a patch. R’ Nechemiah says: It does not require a patch.

[If] nega reappeared on the garment, the patch is saved. [If nega] reappeared on the patch, the garment is burnt. Part of a [previously] confined garment was used to patch a tahor garment. [If] nega reappeared on the garment, the patch is burnt.  [If nega] reappeared on the patch, the first garment is burnt, and the patch functions as an indicator for the second garment.
