Gerard leaned over to look at Cal's hands, his own long fingers reaching out to very gently touch Cal's, gentle and faint and very easy to pull away from the moment Cal might want.

"Fingerprints are very difficult to remove," Gerard comments - if the skin can heal, they'll return. It really is just better to wear gloves if you're a criminal then fuss around with trying to remove prints. "They're similar to Cal's at least. I'd have to see them next to each other to check an exact match though."

Prior to digitally recording and sorting, fingerprints were checked by hand. Having an artistic sense meant you were more likely to be skilled at it, and well - Gerard was very good with patterns.
