Sure, PF drops Baby K on her, the Mother, KB, NEVER calls to see how she is doing, and PF's Mother is like, hmmm, whatever...NOT!
PF's Mother had to know something, and chose, as so many women do, to just ignore the disconnect.
And KK had to have had several talks with PF, in the planning process of KB "missing". Definitely, he didn't just randomly drop off the cell phone and ask her to send a few text messages. She knew EXACTLY what was going on, and she was part of the process. I hope she gets a prison sentence.
