What happened between Joy and Rachel?

I love the energy Joy brings to Rachel’s videos and I’ve noticed her absence lately. She went from being in or mentioned in almost every video to nothing. No Joy around for engagement stuff or Halloween Party or even handing out candy the night before with other friends. Rachel usually mentions when Joy and Dylan are out of town. Something definitely happened there. We’ll see if Rachel mentions Joy in her next video or if she will just disappear like Emily. Also, Rachel has been walking Blaze. Maybe something is up with the dog walker as well? I know she was friends with Joy. Seems weird.
