I was honestly a little irritated that they had absolutely nothing to do with the storyline at all. Regardless of who wants to argue that they were N's guardians, who gives a Hell? Anyone could have been his guardians, but for some reason they designed specific people to watch over him and they did NOTHING with them. In Black 2 and White 2 they are nothing more than two civilians. Literally, that's it.
Nothing about them is special other than their designs and names, so yeah, I think they were really just wastes of data in the long run. :c
