Continuity mistake: During the cold opening scene, Claire's right hand is alternately clasping Ty's left arm or lying flat on the bed as the camera shots change.
Continuity mistake: When Dr. Finn takes the covers off her son, Marcus, the white sheet is still around his legs. It's gone in the next shot, but back on his legs when she kisses him.
Answer: No official reason has been given. Halston Sage has only stated in an interview that leaving the show was not her choice. It is considered that her possible return is "open ended", and while there has been no official announcement, she did make a reappearance at the end of Season 2.
