If I start to disagree I probably don't realize my own autism. So, thanks for the external inside information.DSP is known for being a massive autism magnet, and the user content here frequently shows that being the case.
This could prove Kate's still there but what if "she" is dressed up to a degree of unrecognizability? Darth Vader, a Storm Trooper or Spider (Wo)man? It could be his next girlfriend in disguise. Or "she" lifts the costume and reveals a Rambo cameo.3 weeks until Halloween. Kat allegedly told Phil she wants to dress up. If we see Kat again soon, this will be it.
Or she just puts on cat ears and calls it a day. Don't matter how it will went, I'm kinda hyped for another round of natural interactions with these two love birds. If she will show up anyway, if there isn't a sudden emergency, at the gym, with a helpless naked bodybuilder and only she can free him.
