Well, this is it ladies and gentlemen. We're reaching event horizon territory. The next update is definitely making it to the Community Happenings, and it may even kill the "DSP outlives another one" meme, because either Phil is fucking dead or it would be in bad taste to say that Phil outlived Linda.
The bomb will dropped anytime soon. One final prediction: whatever happened, Phil will use it to stop people from making fun of him.
I wouldn't be so sure.
When Wings' grandma died, aside from refusing to go see her on her deathbed and not going to her funeral because "I don't handle death well" (yeah, because everyone handles death well) and just streamed Dark Souls, he didn't change. He didn't learn to love people, nor it was a wake up call to turn his life around or even make an attempt, and his grandma was more like his mother and they were actually close.
If that fat fuck didn't change, I don't see Linda or Dave passing away changing Phil at all. Not only they aren't close, Phil is incapable of taking accountability for anything.
