Chapter 45-3: Distorted Truths

[LiamKerrington]

my 'rebuttle' to that would be:
then why doesn't Skittles follow any other symbols like the rest of the horde?

Actually, we don't know whether he follows signals or not. After all the cameras made the footage of Skittles being near zombies with them zombos reacting to him.
It could also be the case that Ink used special symbols in front of Skittles which could be kind of uncommon.

it didn't sound like he knew/remembered how he let Ink in to Dunbar, but that is the biggest question for me. i would think ANYone the on-duty guard doesn't recognize at the gate would alert others of a possible intruder.

Sure. Maybe he did not remember how he let Ink in, because at that moment his "zombie-side" had full control over him. Could be similar with what Datu "felt" or "thought", when the symbols took partial control over him. He was not able to describe the meaning or translate the symbols to the survivors - maybe, because this part of his brain was defunct when zombie-Datu was in charge.
Or what YABC has written:

Well, I guess you have to keep in mind that he suffered a severe trauma from that incident. It might just be a locked memory in his mind.

Interesting idea. But in my opinion, a slow-turning Skittles would make some story elements too over-utilized. Just the like the way changelings were at a certain point everywhere around at Deep Space Nine. And it would make him a goner sooner or later, would it not?

Depends. I am not certain anymore that this story-element could or would be over-utilized, if Skittles is a slow-turner. Currently we are at a point of the storyline where there are only these reasons available why a "still human being" exists:
- he has not become zombie-food,
- he has/ was not turned into a zombie,
- he was not shot by other survivors,
- he did not die from suffering from malnutrition, diseases, bad luck.
edit: Which means: It not unlikely that some survivors are slow-turners. I don't think (anymore) that this is just a story-element ... /edit
Also we know that there are three types of infected: the ones becoming zombies, the ones being immune, the slow-turners. But we do not know that, if there is room for more detailed disinguishing.
Another "hint" towards Duncan being kind of a half-zombo or slow-turner could be his smell ...

Yeah, this is what I'm suspecting. He seems to be ignored the same way that Jay ignored Datu after they were both bitten, and the way the zombies ignored Ink after he was bitten. Maybe he is a slow turner too. Even better, if slow turning is a genetic trait then, how amazing would it be if it is revealed that he had a brother in Dunbar with him. A brother named James? A brother named James who escapes with Sean and Hope to the Colony? A brother named James who escapes with Sean and Hope to the Colony but is said to later die from some infection? A brother named James who escapes with Sean and Hope to the Colony but is said to later die from some infection, but was actually euthanized for being a slow turner after biting Tanya?

Wow, haven't thought about such a network on connections.
Somehow I am willing to except that it is a question of genetical disposition. And maybe the slow-turner who bit Tanya was a relative of Duncan's, then yes: why wouldn't Duncan be able to live with the infection for some more time as a human being ... And since Skittles has no one to talk to, he has no opportunity to "understand" what is going on, which is different from the whole Datu-situation ...

Best wishes!
