So what happened is that you did not read Alchemist's hint.
The Alchemist cures two cards to his left and right(4 total).
8 is two cards away from 6, 8 was adjacent to a Pooka.
8 was corrupted by Pooka than cured by a Alchemist.
Plague Doctor corrupted 2 as you can see from the image.
Corrupt Abilities happen before you start revealing cards.
Wait what? Not just the immediately adjacent cards? That was not at all obvious from the Alchemist's description, and makes him much more powerful.
My confusion remains; why is the Plague Doctor not corrupted, despite being next to a Pooka? It doesn't have the Corrupted flag, and is stating accurately that Alchemist is not corrupted. Are Plague Doctors, undocumentedly, immune to Corruption?
All Outcasts are immune to corruption apart from the Drunk who is always corrupted.
Edit: I'd also like to point out that there just was an update and it makes (among other changes) Alechemist's range more clear/obvious.
They state that they corrupt Villagers but don't explicitly specify that it's only villagers, and it's one of those things that are hard to keep track of during the transition from a friendlies-who-tell-the-truth-and-enemies-who-lie paradigm to a friendly/unfriendly-versus-truthful/lying four-option matrix, deserving of special highlighting I think. I also missed that the Poisoner only targets cards right next to it initially, possibly because the terminology wasn't standardized with the # Cards Away abilities.
I think what I'm saying is that a glossary/rules reminder guide would be helpful. :)
