My critique from the last time stands (especially with regards to the object being pretty unremarkable and seemingly stretched thin in order to justify it as an SCP rather than just an anomalous item). I still do not enjoy this. I think the voice you have for this member of GAW is only just barely more believable, though I'm not too convinced nonetheless. Now that this seems to be sticking around; I can buy a member of GAW making this (if the gun had different effects besides "stuff was weaker", which ties back into my original critique of this), but the dialog doesn't seem to be written well.
I'm reading it out to myself and it switches so casually between internet memery and serious grand artsy lad so casually it actually works against the dialog, because I have no reason to believe this 19 year old is either with the way you've portrayed him. Dr. Liam Deets also seems a bit too passionate, particularly when they go on the moral high ground against GAW; there's no real reason with the way you've written them why I should feel like they feel this way.
Still, I think you're finding your footing and that's alright; hopefully you can find a voice soon. I had trouble with that writing for the community at first. I also do like the name "Kektagon", so there's that.
