He's a mess, charred in a few places, the blue light that normally glows from his eye slits and other various spots on his plastanium shell dead and dark. Didi observes with quiet calm, far more sedate than she expected to be standing here in her new lab with the gunslinger finally back in her presence.
Any kind of argument Solomon thought to present to her over the old soldier's return died in that instant of her command. She watched her grandfather's rebellion end in a flare of pride he tried very hard to hide from her but failed. Perhaps it was apparent to him in that moment his daughter's loss came at the same kind of a crossroads and the idea of losing Didi the same way was too much or the old man to accept. Or, he'd already decided to give her what she wanted anyway and this was just his means of appeasing and pleasing her. The quick, reflexive grin of delight he hid behind a cough and a shrug couldn't dim the sparkle in his eyes.
