Thank you for the feedback! I'll try to address your criticisms
Picture- yeah, haven't been able to get that yet, file uploads give links that say the picture doesn't exist :P
xxxx-1 vs xxxx-2- I'll definitely make more clarification, but my intent was that the extra size and style was a normal part of xxxx-1, so I'll get rid of the "From SCP-3363-2" part, didn't think about the ramifications there
Comparing languages- I'll create a bigger separation from xxxx-1 and natural languages by changing my wording
Passing out- definitely didn't think about that, thank you for letting me know, I'll create a workaround or implement it into the anomalous effects of xxxx
Friend- Friend knew about the effects (anemia, obsession), but didn't know what caused it.
I'll include how long xxxx-2 has been at Harvard
Tried to imply that the pen and the student weren't found before the student's enrollment, implying the student had it upon their enrollment, but I'll definitely clarify that.
Death of/who is xxxx-2- xxxx-2 definitely died, but I should've made the D-Class personnel an scp if it makes you more obsessive. I added the obsession later without much thought, so I should've thought that through more
