This iteration still isn't doing it for me due to, what seems to me as, completely nonsensical actions on everyone's behalf:
Aside from the ludicrously contrived notion that any random person can simply walk up to the front doors of a clandestine organization, intuitively knowing what it is they do (which, again, I'm certain you can find a better way to get the item into the SCPF's hands); I'm left wondering why the flag was created like this to begin with.
As I said with the last version, more context should be applied to the brothers, instead of shifting the focus to concentrate on justifying the SCProcedures as you did here, because that still makes little to no sense. Why, if this seargent is being affected by the skip, can they not just amnestize/give him counseling? Why permanently lose one of their personnel to contain a Safe-class item? Especially when there's nothing stopping mundane rememberance of the individual? I can't suspend my disbelief when these things keep piling up, especially for an item that just forces people to care about something.
If part of the initial idea here was dealing with grief (IIRC, you said something to this effect on the previous page's discussion), then it could really use a shift to focus on the POI, and perhaps play with/tweak the effect because his motivation is completely obscure beyond "but we have to remember 'cuz reasons":
For instance, say you examine how he reacted to his brother's death. Could it be that he felt nothing? Could he have felt guilty for under-reacting, and created this as a means to masochistically force himself to feel? Some people do become withdrawn emotionally when faced with loss, and some people in this situation can reach the conclusion that there may be something wrong with them, for being incapable of expressing their grief in a visible manner. So maybe explore something like that?
Or, if we're trying to figure out a more sensible way to handle the containment, maybe shift the anomaly's effect a bit? You could perhaps tweak the effect in such a way so that this overpowers all memory of Evan to begin with. This might entail shifting the primary designation to an antimemetic soldier, with perhaps some residual, observable impact on the world the SCPF investigates to discover the POI and the flag (which would go a ways to fix my issue with the recovery as well, and solve the issue of "we can remember him just fine without the anomaly, why are we exposing personnel to this?").
Another downvote unfortunately, as there is a stronger story waiting to be told here.
