The Sister - S4.E6

Debra is upset when her hippie, free spirit sister decides to become ... a sister. It's a good indication that something is up when Debra's sister, Jennifer, shows up for a visit with rosary beads and prayer cards as gifts for the kids. Unable to share the real reason why she is so upset with Jennifer's decision to become a nun, Debra reacts by accusing her sister of going through yet another phase and not being truly worthy of the calling to the religious life.
