Bull shit it's not a plothole. I respect your pacifist viewpoint but trying to invalidate my argument with no evidence? Nah, it's a fucking plothole. You guys so ardently trying to tell me it's not a plothole has just made me double down. Prove it's not a plothole and I'll back down, or just move on. Stop trying to tell me it's not a plothole with zero evidence.
I honestly don't even give a fuck that the plothole exists, I just wanted more info, but for some reason you fanboys/smurfs decided to try and gaslight me instead.
You can't prove a negative, so "prove it is not a plot hole" is not possible, but I will try to argue as to why I don't think it is. A plot hole presents itself as an inconsistency in the narrative, or in a character. Claire not having her necklace with her at home is most certainly not a plot hole, because it is not inconsistent with anything that was said or shown in the story. It would be a plot hole IF, and only IF, we had a dialogue saying that it was mandatory, or at least common practice for every single employee of the Order always carries their equipment with them, which was never said.
The Order functions in a way that is similar to the military. And in the military people don't take their service weapons home, when they are not serving, their equipment is stored in the military armory. And the imbued artifacts are even more important than weapons, so there is logic to why they wouldn't be allowed to carry them at all times outside of when they are serving.
Also, on another argument entirely, these people only need these imbued artifacts when they are investigating and hunting for Dark Ones at the orders of the higher ups. In the same way that military personnel don't need to take their service weapons home (and they can't anyways), the people of the Order don't need to take their artifacts, because they are off duty, they would not be out hunting for companions and dark ones, just as soldiers would not be out hunting criminals on the street when they are off duty.
Even if there was a danger of them being attacked in their homes by some disgruntled Companion, which again, was never mentioned in the game canon, a single civilian with no power would not be able to fight back anyways, and the only result would be them dying and artifact being lost.
And just as a final point, the Order employees were able to detect MC as a Companion when he was using Nael's pearl, and other Companions were also able to detect him. So considering that imbued artifactss are pretty much the same thing as Nael's pearl, just weaker, it would be pretty possible that those things could be detected by other Companions, which would put these people in jeopardy while they were unprotected at their homes. So yes, there are a lot of logical reasons, and precedent, as to why Claire wouldn't use her imbued artifact at home.
I hope you can consider my arguments without anger, and without believing people want to gaslight you. At least, I don't.
