Season two of 7th Heaven ended with Annie Camden (Catherine Hicks) informing one and all that she was pregnant. Season three begins as Annie learns she is to give birth to twins -- who in typical TV-series fashion ultimately arrive amidst much chaos and confusion, just in time for Valentine's Day. (At first, twins Sam and David Camden were played by real-life quadruplets Nikolas, Lorenzo, Zachary, and Myrinda Brino; after two seasons, only Nikolas and Lorenzo would continue on with the roles.) In other developments, Annie's widowed father, Charles Jackson (Graham Jarvis), weds his longtime girlfriend, Ginger (Beverly Garland); 18-year-old Matt Camden (Barry Watson) is kept busy with Shauna (Maureen O'Sullivan), an old flame who has come back into his life; and 14-year-old Lucy Camden (Beverley Mitchell) has accumulated two new beaux, Rod (Toran Caudell) and Jordan (Wade Carpenter). The season's two-part finale finds Matt getting depressed over the wedding of his onetime sweetheart Heather (Andrea Ferrell); younger Camden son Simon (David Gallagher) undergoing his first love pangs, with Deena Stewart (Nicole Cherie Saletta) as the object of his very ardent affections; and there is news of yet another pregnancy in the family.
