It could be, but my hunch is that it is pure coincidence. Zarf had the magazine picture of Zach's mom, and that is highly questionable. But he also had about 100 other images of women he cut out of magazines too. I am thinking that he got the picture out of a very old magazine (maybe it was one of his mom's old magazines.) I think perhaps he just saw something he admired in her. He probably collects these pictures as inspiration for what kind of woman he wants Zoe to be. I could be wrong, though.
