On Criminal Minds
When she was an infant, Meg lost her parents during the 9/11 terrorist attacks. As a result, she was raised by her maternal aunt Kate and her husband for the majority of her life. She is introduced at the end of X, when Kate returns home after solving a case with the rest of the BAU and finds her sleeping on the sofa while trying to do her homework. Kate wakes Meg up and tells her what time it is, to which Meg tells her that she has been gone for two days. Kate then tells her that she loves her, and Meg responds that she loves her too.
