After the formation of the International Temporal Enforcement Agency the pair were teamed up, focusing more on "hide and strike" missions as Miranda specialized in espionage while Hui was skilled in tactics. The duo proved to be quite effective, their investigation of the Fortune Sea Resort ensuring that dozens of people weren't held for ransom, including ITEA friends Erika Stone and Caitlin Trafford. The pair also did a great deal of investigating during Ashley Tisdale's return, though their ultimate aide came in forming a tactical team. After the Tisdale incident Suzanna Ortiz and Sophia Katsopolis temporarily joined the team as Team Alpha had been disbanded. The four worked on tracking Type-7 activity in Hong Kong, eventually discovering it was linked to human trafficking.
