[Agent Tape]
Replacing Miguel was no small feat, but Martinez, a seasoned tumbler with crack skills, quickly rose to prominence. Turner, we just confirmed his contract renewal. He’s been with us for ten years and he’s proven he’s got the organizational skills necessary. Sinclair got promoted this month to head the team, and he’s doing a great job so far. Would burn through a lot of money, that deal with Aaron, but so far that has brought solid yield. Overall, everything’s looking up after some recent turbulence.
