After Barry turns down the offer of Pattys homemade chicken and noodle soup, its a bit of a kick in the crotch for Patty when she finds out that Barry is all about Joes soup. Seemingly Detective Joe West, as well as being an ultimate father figure, is also a pro when it comes to knocking together a batch of homemade soup. Either that or it was just a convenient exchange to throw a spanner in the works of the budding relationship between Barry and Patty. Either way, I prefer to think of Joe being some sort of master soup chef.
