Lemme help you out.
The 'proof'(if you can call it that) he is talking about is the following:
-Malcom and Peridot both using the term 'brb' (usually following a line break)
-Peridot mentioining Derek when no one else has had mentioned it (However it was mentioned once in a Neg)
-Malc admitting he was Peridot (jokingly, quoting Drake)
-And the main one, Malcom responding to a post from OG_StankBref's that was directed at Peridot
Which was very strange due to Malcom's demeanor of passive bystander up until then.
I"m not saying you are Malcolm, PeridotPuss. In fact, I think you are who you say you are. I'm just compiling all the "evidence" for those who do not want to read through 50 pages to find it.
I'm on my referee status in this thread
