7th Heaven
We Do (7x18)
: 21, 2003
When a nasty thunderstorm rolls through the region and threatens to postpone Lucy and Kevin's wedding, everyone scrambles to make it to the church in time. Mary (guest-star Jessica Biel) barely catches the last flight in and brings a surprise guest with her- Matt. Chandler and Roxanne rush to pick up Ben and his mother (guest star Bo Derek, "10") who are stranded at the airport in Las Vegas, but tensions run high and a fist fight breaks out; and Matt (guest star Barry Watson) gives Lucy some very special brotherly advice when she confesses to pre-wedding jitters.
