A Snow Mountain of Trouble

Meredith's birthday party comes to an icy cold ending when Jen and Mary get into a heated argument about Mary's insensitivity towards Jen's aunt, and Whitney confronts Lisa about an incident at Whitney's vow renewal. While Meredith battles marriage problems and Whitney helps her dad through a difficult time, Heather invites all the women to a ski day, which starts out well, but goes downhill when Whitney and Heather confront Lisa about her judgmental behavior.
