Probably not. I think she'll take the path of Leanna and drop off the face of the earth and just focus on herself. She barely wants anything to do with Phil and his fans now, and I think even she knows better than to try and explain something to Phil's paypigs. I imagine when she does move on, she'll have another relationship lined up as it is, so she'll just wait to focus on her new provider and not risk getting pulled into DSP drama.
I can say a lot of negative things about Kat, but I'll give her credit for doing everything she can to limit interaction with DSP's online orbit, whether supporters or detractors. I'm sure if Phil had his way, she'd be "trophy" girlfriending every stream and appearing in more instragram posts, but she knows she'll be hounded by both fans and detractors so steers clear. Not to mention she seems to find Phil's streams just as boring as we do.
