While the KC arc has seen Phil go totally unhinged on his own streams, the joint streams have been rough. Why? Because KC found out that "glazing" Phil and pissing us off was the only way to play it, and it gets old fast.
If you watched the "Chained Together" stream, besides sucking at the gameplay, Phil adds nothing. PPP tried praising Phil, and Phil smiles and laughs. He tried sneak-dissing Phil, and Phil ignores the comment or changes the subject because he wants those tips. DSP just provides no entertainment value. The only thing that gets a response is if you ask direct questions to Phil about Phil---that's a topic he's interested in. But he's an empty shell of a human, and they've found that out. So the only entertainment value left is stringing him along with constant compliments while doing the King Phil routine.
