"Fair point, hey J?" The barest beginnings of a learning program, but he knows enough to get this message typed up and sent to the right people. Tony scans the page with a flick of the wrist as a clipped, formal English voice crackles to life from a speaker on the table.

"Sir?"

"We need a deep dive on this file, Military, medical discharge, send Howard the scan I took and tell him something's fishy going on in medical military contracting. I was pretty sure he had that all wrapped up in a neat little bow but this mess isn't his work." Much as he and Howard disagreed on...everything? The man took pride in his products and wouldn't leave a soldier walking around with steel bolted to his ribs. "Also send a primer to Banner and Cho. Poke Pep to poke the Lawyers, too, while we're at it."

"Stirring up trouble again, sir?"

"Probably." Tony sets the page aside and squints at the arm's design, pulling up a blank mockup without next to it. "Right, first thing- the core is too heavy for your bones. There are standards weights and materials for a reason, your spine is one of them-"

Like an artist he pulls out and slides into place hollow bones of polycarbon, something strong and light that will do the job without twisting everything around. "Huh, this? Holographic drafting table, high fidelity handheld 3d scanner, it's pretty basic stuff-"

For his lab, at least.
