Soap opera rapid aging syndrome (SORAS) is the practice of accelerating the age of a television or film character in conflict with the timeline of a series or the real-world progression of time. This allows, for instance, storylines around a pregnancy and birth to be relatively quickly followed by storylines around the travails of that child as a teenager or young adult. This is usually accomplished by recasting the actor playing the part, although in some cases the character is not shown onscreen, only mentioned, until after they have been "rapidly aged".
