Exactly in the weeks of Sefer Devarim, exactly in the Chalal, we read the Haftara out of Sefer Yeshayahu. This is quite fortunate, in view of this post.
At the very end of Parshat Ki Tetsei, we read Parshat Amalek. So really, this Parasha, Ki Tetsei, does not belong to the Chalal. Its Haftara is from Yeshayahu 54, and ends with verse 9 and 10. Again there is a fortunate aspect to this, as Yeshayahu 54:9,10 does not belong here, or there, or anywhere. A copy "error", we assume. The pairing with a Parasha that is not in the Chalal is therefore fortunate.
Hashgacha, that is what it is.
