What was going on between them?
Well, 'between them' is the strong word since Metokur mostly ignored this shitshow. In short, Null didn't like him much for some stupid reason around 5 years ago, but at some point Jim tweeted(yes, he wasn't banned at that point, I think it was his second account before Quarantined Coof) about Tommy Tooter going apeshit on stream and this caused some people to join KF and shitpost on his subforum. Keep in mind, that he didn't encourage anyone to do this, he just laughed at him, but it caused Null to lock sub and go apeshit on Twitter like "it is joyless" and shit, while blaming Metokur for that.
Then Montagraph happened. If you remember, Metokur just laughed at him for acting like he has some real power while he is just sue-happy litigating schizo boomer. At some point Jim retweeted someone mentioning that Monty either claimed to have CP or that he had been involved in some pedoshit and said "it goes darker and darker". For some reason Null and his dickriders claimed "OOOH HE CALLED HIM A PEDO" which caused Null to write OP for Monty's thread where each paragraph ended with "LOOK HE IS NOT A PEDO". Embarrassing stuff, really. If he really called Monty anything close to this, he would be now next to Ricky in court. He then claimed that Metokur wasn't streaming because he was afraid of Monty, but now I think it is obvious that he had more reasons.
Then Ralph farted on stream. If you were here at that time, you know how stupid it was, since every gunt hater was running around screaming how funny it was and how everyone should laugh at him otherwise it is guantguarding. For over a month they were sending superchats to Jim to make him talk about it and if you know anything about Metokur, he hates to be dragged into anything just to fight someone else's fights. After some time he just commented "yeah, it seems that he farted, maybe he shat himself, idk" and of course it made those retards go apeshit, including Null stating "seeeee. he has internet friends!" I don't need to explain to you that it wasn't the case.
And to preface your question, no, to my knowledge Metokur replied only once and it basically "people keep tagging me that Null doesn't like me, wtf is his problem?"
