With no ties and no connections for Rossi, there appears to be no settling down for this 3x divorcé. However his—and all Criminal Minds' fans—hearts melted like butter when he found out he had a daughter with short-lived ex-wife Hayden Montgomery. This episode definitely brought Joy into the lives of Rossi and every fan of the show. Pun fully intended.
