Due to a misunderstanding Rosie and the vicar invite themselves and Caroline asks Sal along to mind Rosie. Other than Susie, the other guests are very late, due to rail delays, and Sal gets Caroline to watch her son's video message home, which produces tears all round, Rosie being the unexpected comforter.
