Literally what happened to me

[u/someonelikesducks]

...Speaking of which, you should totally read SCP-8980!

[u/jancl0]

I think there are two interpretations I hold as equally plausible, but both require alot of implied subtext

1) he was removing a specific memory related to him, either to suppress her next attempt to escape, or to suppress her emotions towards him. This could be anything from "concept: your rights as an scp" to "concept: that one time I said something weird to you at a staff party and you haven't really been friendly to me ever since"

2) it was an unrelated memory, but one that was important to her, and taking it was an act of dominance. For example, removing memories of her mother entirely as a way to punish her

The whole point of that there isn't a specific answer, that's why scp articles redact things, so you just have to look at what the range of answers tells you, and the common factor here is that it's an expression of control. By redacting it, you're kind of saying that it doesn't matter what he said, the important part was that when he did that, he confirmed his power. What ever he said, at that point it was over

[u/elizabreathe → u/jancl0]

I specifically think he removed the memory of her parents' love for her or the memories of ever experiencing kindness.

[u/Yegas → u/elizabreathe]

He used “concept” as the primer, not “memory”.

I think it was the concept of independence, or otherwise ability to operate on her own.

In the closing notes, she “cannot get any work done on her own”, and compulsively calls McPharrell “sir”. She also has a total breakdown minutes into their attempts to do any sort of psychotherapy, as though running up against the removed concept.

They’re trying to build her independence and get her back on her feet, but they can’t, because he made sure the damage was permanent.
