It's too soon after the Lex arc for the writers to introduce something completely unexpected. It's most likely just some imagined or exaggerated struggle he's using to fish for tips lately.
To be fair, the Lex chapter was meant to be filler to setup the August saga since it came out of nowhere in the original, but the adaptation was very well received and Lex got more attention while the August saga kinda died as it came. I have hope the writers are using it to setup a future meltdown, we shall see.
So Phil says he might do a modded Skyrim run but doesn't know how. Isn't Kat is a huge (lol) fan of the game? That sounds like the perfect game for a "chill" co-op playthrough, or at the very least something to talk with her about.
My guess though is he'll probably take one of theses Vortex packs you can one click install on nexus.
And it's still very likely that Phil will fuck it up because Skyrim has like a dozen versions and modpacks tend to be very specific.
Maybe it's because I'm one of those autists who sometimes has more fun modding games than actually playing them, but yeah, you do need to have at least a basic sense of curiosity to understand how a game works. Phil being Phil would naturally either install a basic modpack that changes virtually nothing or a big one and just do a vanilla run even though he added a shitload of new features and quests.
For me, watching Phil trying to understand a mod would be gold just to see the sheer level of stupidity and him completely shutting off the second he sees any kind of mental challenge.
This is a special one, PPP was a "friend," a friend who's last fun razzing grill phil segment went and shattered his glass house of delusions like Adam with SS just worse. So he's down bad cause his friend was a little too truthful with him. So he goes to the old faithful pity "secret emergency" and here we are.
I think this is it.
I think Phil is just too socially fucking retarded (descriptive) that he can't understand sadness on a logical level, but he feels it on an emotional level. What I mean is thus, Phil can say he doesn't care all he wants, but a combination of Lex making him look like a bitch, Rich tattooing his face on his asscheek, his old Team Hate pal curbstomping him in his precious ST2, the August video and little things like that do affect him since they happen one after another. For most of us, it's the little things building up that get us, like getting late to work, some asshole cutting you off in traffic, stepping on dogshit, forgetting something that had a deadline, you get the idea.
Despite how alien Phil is, he's still a human, and one who also gets affected by these things, but I also think he's so deluded into his "I don't care, I'm the king" worldview that he can't logically put into words what upsets him so much. He knows something bothers him, but he's incapable of that basic introspection we all have where we say "yeah that fucking 6'10 asshole bumped into me and I'm upset because I wanted to say something but I didn't and now I feel like a fag". Phil is incapable of thinking "yeah that fucking slut felted me, Rich is making fun of me and now Ashton is calling me out even though I wanted to cancel that segment" because his logic dictates that he copes by twisting it into something else, but he still feels the raw emotion of being humilliated and emotionally emasculated repeatedly.
With that in mind, I think Phil is looking at his current tax situation and thinking it's the end of the world. Not because it is, but because his self-esteem has been raped so much that he is now in coping overdrive. Basically, he's being a little bitch, even more than usual.
