The Tudors/Heartwarming


 * Most scenes between Mary and Elizabeth. Specific ones include Mary comforting baby Elizabeth in season 2 (extra points since Mary has every reason not to care if this particular baby is upset), the two sisters snuggled in bed and talking about their new brother in season 3, and Mary telling Elizabeth that they've both been restored to the succession in season 4.
 * Any scenes between Katherine of Aragon and Mary or Anne Boleyn and Elizabeth.
