Alejandra "Alex" Vega is an ex-Belltower pilot. She had to leave her previous job in a hurry after she helped Ben Saxon expose Belltower’s illegal drug operation in Panama. Through Saxon, she was introduced to, and joined, the Janus Collective.
Now she’s supporting Jensen with his investigation into Task Force 29 in order to determine if they are, in fact, a puppet of the Illuminati. She facilitated Jensen's entry into the Task Force, and acts as a go-between for him and Janus.
