Hey I just had this thought. Since Idina Menzel played as Shelby which is Rachel's mom, so that makes her sort of Jonathan Groff/Jesse st. James' mother-in-law. And in Frozen(2013) Idina played Elsa which becomes like Anna's mother figure in the movie, and Jonathan played Kristoff who later marry Anna, so Jonathan is Idina's son-in-law again! Hahaha
