Nature of Nero's Devil Trigger

[Picard]

OK, so Nero's Devil Trigger in DMC4 is not his own, but rather requires Yamato. It also appears as a blue doppelganger. So what if that DT is actually manifestation of a fragment of soul - either Sparda's, contained in Yamato, or else Vergil's? If Yamato contains a fragment of a soul, then Nero's Devil Bringer might have acted as a conduit which let Nero's own soul connect to soul fragment in Yamato.

Thoughts?

It's basically the oldest theory, which has been going about for years now. At this point I'd say we can take it as a good one.

Thanks. I guess I had just forgotten it even if I had seen it before.

im a bit late but it just awoke his soul itself and it manifested as the blue thing that looks like vergils dt.
