Scent is indeed another thing. A wave of joy and relief washes over Erek at the sight of someone walking a dog, and he's quick to make sure he's covered in human hologram complete with forcefield. His new immediate goal is to say hello to and pet New Moon.

He doesn't smell human, but neither does he smell threatening. He smells like... not much. Metal doesn't have a strong smell. His holographic face is smiling as he approaches. "I'm so glad to see a dog here," Erek calls out to Saix. "I thought they were all... gone."
