When she returned to her space, Sunshine was surprised to find Tank in the hearth working on the ring. Hunter was at his side, barking about how he was doing it wrong and ruining everything.
"Hello boy..." She looked at Tank. "And girl." She nodded at Hunter.
Tank stood up and she took his place. He had already cooled the solid ring, added gold and red rubies.
"The recording mechanism is wired into the gold." Tank told her.
Hunter grunted. "I told him it was a bad idea. It should have been embedded in the rubies. The gold encompasses the whole ring. If someday the recipient wants to throw away the recording, the ring as a whole will have to be thrown away. On the other hand, if it is in the ruby, only one gem is removed and replaced."
"But it will be visible in the ruby." Tank argued back. "I was built for construction and repairs. You are a security guard. Perhaps we should all stick to our areas of expertise."
