5 years ago, Lexa Matthews left the BAU after Emily Prentiss, Unit Chief of the BAU, broke up with her and told her she never wanted to see her again. So Lexa accepted a job at Interpol. Eventually becoming the youngest Head of Criminal Investigations. Now Lexa is returning to the States after being transferred to the DC Interpol office to work alongside the BAU as a permanent consultant when needed. Lexa has remained close with the rest of the BAU team over the last five years. Constantly texting and video calling Morgan, Reid, Jareau, and Garcia. How angry will Emily when she finds out Lexa is back? Especially when she sees that Lexa is 4 months pregnant.
