In so many ways because not only are we introduced to caroline but we also get a glimpse of how much Booth and Bones respect each other.
Another reviewer talked about Booth being judgy.. yes, well, he gets really defensive when people talk about his religion or about military men. The point there is to make him more human with flaws so people can relate and like. Cause we all know how protective of his friends he is. Even when Bones was starting to doubt herself, he never did.
Other 2 points to remember are the development of booth and bones relationship and the start of something between hodgins and angela.
