People seem to be calling him out a lot more these days, and pretty much all he does is e-beg and show off the spoils of his e-begging. Even by the low standards of troons, he comes across as a crazy oddball. Most people seem to ignore him, and even Greta seems to merely tolerate him when he posts some off-topic ego trip. What is probably going to happen fairly soon is that his usefulness as a pawn will end because any opinion he ventures will be tainted by association.
In Greta's case, what will happen is that she'll stop acknowledging him altogether. It was quite noticeable that she didn't respond to Phil's excited yapping when she mentioned going to Portland, so she clearly has no interest in true friendship. She'll stop sharing his e-begging posts and ass-patting, which currently seems to represent the extent of her help. Phil probably won't notice until she blocks him, whereupon he'll be crushed and we'll get a lot more stories where he kills Kiwi agents with his bare hands and flushes their phones down a storm drain.
I don't think Greta wants to actively harm Phil, but she's too much of a narcissist to give a shit about hurting his feelings if he no longer serves any purpose.
