Sonny had asked Data to meet him at the teleporter room before he and the others beamed aboard the Charleston. When Data arrived, Sonny handed the android a small box. "Since you helped me make my guitar, I thought I'd return the favor," he said.
Data opened the box to find a miniature guitar no bigger than fifteen cm tall sitting on a little plastic stand. It had his name emblazoned on the front with bright holographic stickers.
Data looked back to Sonny. "Thank you," he said, before adding, "though I do not understand its purpose."
"Don't ya have knick knacks in the 24th century? Like, erm," he said, struggling to describe it, "like a memento. Something to remember someone by."
"I have no need for such items," Data said, "as I can recall everything that I have ever experienced, if I so wish."
Sonny shook his head, smiling. "Well, just on the off chance that you can't," he said. "Anyway, the doctor told me that it was you that made the call to bring us back to the ship and wake us up. I never thought I'd say this, but thanks. I think I've decided that I rather like being alive after all." He abruptly grabbed the android by the shoulders. "Don't let all the rest of them get too stodgy, okay?"
Data made a mental note to look up 'stodgy' later. "I will try my best," he promised.
