Meg Callahan

Meg Callahan is the niece of SSA Kate Callahan, who first appeared in X.

On Criminal Minds
Meg was born sometime in 2001. Her parents were employed at the Pentagon in unspecified jobs. Both of them died alongside hundreds of others when American Airlines Flight 77 crashed into the Pentagon during the 9/11 terrorist attacks, which ultimately claimed the lives of almost 3,000 people. As a result, Meg was raised by her maternal aunt Kate and her husband Chris 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. In A Thousand Suns, she calls Kate after the latter finishes the current case.

She reappears in The Boys of Sudworth Place, having a phone call with Kate while sleeping over at the house of her friend Markayla Davis. After she hangs up, the two express their dissatisfaction with homework before receiving a response from who they believe to be a male high-school student, containing a picture of a muscular teenager. The user asks for a photo of them in return, and the two pose for one despite Meg's reluctance. It is then revealed that the user is actually an older male, who responds to them with a post saying they "look gorgeous".

Meg then reappeared in Scream, in which she and Markayla plan to go to the shopping mall with the intention of meeting up with the "student". She lies to Kate and Chris that she and Markayla are seeing two classmates, which still worries them. By the end of the episode, she meets up with Markayla before they suddenly have an awkward encounter with Chris, who was secretly spying on them. It is then revealed that the man they have been contacting was about to meet up with them in person before being interrupted by an unknowing Chris. The man shoulders Chris and goes to his car, texting Meg that he couldn't make it, which disappoints her and Markayla. He then angrily tosses the phone into a bundle of rope he had with him, signifying he had been planning on abducting at least one of the girls.
