The “Sara” being cast is only being cast as a temporary lookalike to SWC for the purposes of the episodes leading up through Ep.03×03. The actress will have shadows blocking her face or her features will be turned away from the camera during filming in order to camoflauge her as the real “Sara.” Sarah Wayne Callies is NOT leaving the show and will be back filming for Ep. 03×04. Although SWC will be on maternity leave, she has already taped voiceovers in order to keep Sara’s voice the same as the director and producers want to keep the stand-in as secret as a stunt double is in the show…ultimately hoping the audience doesn’t notice a thing different about the two Sara’s.

Due to the casting of the temporary “Sara” stand-in lookalike, SpoilerFix is probably thinking they are casting a new “Sara” when really all they are doing is hoping to find a good actress who looks somewhat similar to SWC until SWC’s maternity leave is over and she can return to the show. Therefore, don’t fear…SWC is not leaving the show at all”
