And of course, it has nothing to do with gathering memories as well, because Arclight already saw that through Arca. Inside Cruz's brains there must be something that was placed there, maybe the time he received medical treatment from Mengroze.

If you remember, there was a discussion earlier about how Setsuna and Kuchinashi were most likely acting on their own by attempting to kill Cruz.

Even so, according to Ynot's translation Arclight mentions that Cruz's head is 'a good place to hide something', which suggests it's something he didn't have originally.
