Seed of Evil: same scene with cook in Rot Warren again?

So I have gathered that you can revisit some old map locations in the Seed of Evil expansion, to earn more loot and XP.

But I’ve entered the Rot Warren and it’s all the same again as in the original game: same dialogue, they want to eat the cook again, who informs us he “tastes like shXXXt”.

Is this normal?
