10x18 - 7th Heaven

The Camdens receive official invitations to Simon and Rose's wedding, and to their dismay, they learn that the date conflicts with Matt and Sarah's graduation from medical school. As this news creates a tailspin with the family, Rose stubbornly refuses to change the wedding date. Eric and Kevin think they have a solution to the problem, but when Annie disapproves of their methods, she looks for help from an entirely different source. Meanwhile, Ruthie wants to enroll in a summer program that takes place in Scotland.
