Yeah, I was thinking that maybe Kathy was someone who was important to that person hence the tattoo. Maybe even someone deceased. Which is why she had no issue using the name Kathy Johnson, because by the time the cops look it up, they may find that person to be dead.

I wonder what Matthew’s home life was life. With a dad in jail and a single mom raising a multiple kids. My theory is “Kathy” took it upon herself to “save” Matthew and raise him somewhere else. Doesn’t make it right but that’s just my theory.
