Agba was a quaddie in welding and joining; one of Leo Graf's students. He helped to disassemble the Cay Habitat and rearrange it into a form suitable for a space ship. When clamps holding modules of the habitat proved to be welded to the habitat (due to spontaneous vacuum diffusion welding), he had to take on the job of cutting them and finding replacement clamp-like tools for the new configuration. His friend Tabbi's solution, of using slurry explosive to blow the clamps open, sped up their work quite a bit and enabled them to reuse some of them, but it also led to them using up the explosive just as Leo was going to need it for his own construction project.
