Riser Egg in Halo 4 FUD?

In this weeks Bulletin Greg Bear mentioned Halo Crytum character Riser. After Reading the Bulletin I remembered something I had seen in the FUD wreckage in Halo 4 campaign. Could this be a reference to Riser? If so what does .1015.10 refer to?

It’s probably someone’s son or daughter.
Vic’s son showed me his Easter egg and I found his sister’s. So it looks more like someone’s kid.
