For an example of Phil's 'bowed out' posture, look no further than the Project 7 intro.
Also, shoutout to that sweet cellphone holder.
Phil does appear to have lost weight, but his body has completely atrophied. People were commenting on the saggy moobs and the shoulders, but if you match those with the noodle arms, the delicate shoulders, the paunchy belly, and the gray, patchy goatee... Phil has the body of a grandpa. Or, more disturbingly, a grandma (minus the facial hair). He has endured NO physical activity since moving to Washington and barely has to waddle beyond the house. Phil was probably healthiest between girlfriends because he had to do all physical activity around the house himself.
A point of reference from Google images:
My apologies to this poor lady. Her hairline held up better than his, though.
On the topic of Kat, I think the bullying story was entirely fake. I agree with everyone who is suggesting that she likely left to a Halloween party, and that the salty Phil opted to use that as a narrative to go after Tevin, which he requires. Tevin is a bigger issue than Fred ever was because of the success of Tevin's restreams, but Phil's history with Tevin is less black and white, as it were. He implied Tevin was banned for restreaming on Twitch, and I think he was suspended once, but Tev was permabanned for 'harassing' Sidella, as far as I know. Phil can't touch this story because Sidella is trouble. He is a mentally handicapped guy that Phil has exploited for money, and he instigated a conflict with several racist tirades that subsequently also got Sidella banned, something that Phil has made verboten to mention. If Tevin hurt Kat, however, that would put Phil in a sympathetic position to try to finish the job.
I think someone of note shoulder tapped Phil and warned him that his attempt to rally the troops was too obvious and he needed to drop it immediately, before his Twitch overlords came down on him. That's why the narrative has basically shifted back to Kat returning to streams and having left of her own volition.
