- "Vega, clear the perimeter. No press for a hundred yards."
- ―Daniel Sousa
Vega was an agent of the Strategic Scientific Reserve branch located in Los Angeles under the command of Daniel Sousa. Sousa had Vega accompany him to the Wilkes Residence to investigate what connection Jason Wilkes had with the men who tried to kill him and Peggy Carter in Isodyne Energy Headquarters before an explosion occurred. Since reporters were surrounding the residence when Carter arrived to help in the investigation, Sousa told Vega keep the press away from the crime scene.
Vega went into the bedroom of Wilkes and found a gun of the same make and model as the one that had killed Agents Beringer and White the day before. As Vega went to report his find to Sousa, he overheard Sousa and Carter discussing why Wilkes had a Russian passport; Vega accused Wilkes of being a spy. When asked for evidence of his accusation, Vega showed his find, but Carter did not believe Wilkes to be a spy because the evidence was too easy to find.
- "Poor Violet. Doesn't realize she can do better, huh?"
Vega and the other agents in the Auerbach Theatrical Agency learned that Daniel Sousa asked his girlfriend Violet to marry him and had a gathering with pie to celebrate. Peggy Carter arrived and asked what was occurring; Agent Ryan informed Carter while Vega teased Sousa. Vega continued to eat as Sousa and Carter stepped away to talk.
