Leo notes that now York's rephrased from humans to organics. Perhaps he should be honored by the inclusivity.

"...Well... I was going to help you, but then you told me to fuck off, so I kiiinda got the picture that you didn't want me there."

And Leo hadn't tried to reach back out after that, because why would he? He doesn't know why it was on him to do that, after how that conversation ended.

"Me and my brother have been looking into it, too. That's how we figured out Stu was involved. Or did you miss that giant trainwreck on the Peanut party?"

It was broadcasted live on the network, so it's totally possible York could have seen it.
