Not sure if anyone has seen this, or if I’m late but there’s a picture of Guilty Spark in Master Chief’s visor. I noticed this when I got a huge poster of the cover for Christmas.
(His visor was always suspicious; it intrigued me)
Anyway, here’s the picture to zoom in and look at:

NOTE: This may as well could be any Monitor, I’m just assuming it’s 343 
Also he’s in between the A and L.
I now think there should be a Where’s Guilty? book.
Kind of looks like a mirrored-GRD Helmet Visor if you look close enough. Perhaps a clue?

It was originally the Marathon symbol, and that’s owned by Bungie, so they had to change it.

Oh, whoa. I see it now!
