The concepts that created it are R&D genius, but nothing that he can truly understand outside of "hologram" and "fake solid surface". He knows how to turn it on and off as easily as he can put effort into holding his breath. But he can't explain how his arm works.]

They've got a good medical team here. [He puts that unusual hand on Dorian's shoulder.] Didn't mean to worry you.
