anyone like me wondering y usutu was even in the episode..?
i dunno if its part of some grand master plan..
but the dude's dead!
and even without him in that episode.. i believe that parkman would have been able to find angela..

besides it seemingly having no relevance in the episode..
i think that it's just a waste of money..
i'm sure that he also would have been paid for 'guest starring' for that episode..

could this have been part of a bigger plot..?

It isn't normal that a dead guy appears like that, so there might be something we don't know with either Angela's or Usutu's power. (or someone else)
Angela have been one of the most mysterious character during the whole series. We know almost nothing about her. Is she good, evil, neutral?

It’s been speculated that his power is more like Astral Projection, while the Precognition is more like the result of using that paste stuff like his ancestors. Although it has also been said that Usutu’s paste is like Isaac’s drugs, but I wouldn’t be surprised if Usutu still appears… I mean in theory, if you have the power to let your spirit leave your body, then your mind/ soul could technically live on after your body dies.

It's not the same ability, but it worked for Hana in the GN's...

Hmm, yes Usutu's power does seem to fit Astral Projection more, and he can pass it on by that paste... to others, hence all the Spirit Walking...

I was wondering this same thing, janjing

I bet it is just Angela's doing, like how she was able to appear to Sylar in his dream. She can probably get in people's heads and make them see what she wants. Hopefully this isn't exploited, however, because I'd rather her not become more of a main character (never cared for her)

It was arthur that made Usutu appear, the same way he was in angela's dream while he was in his office, i think he partially exists there when he needs to, as for Usutu, he is really dead, there is no resurrection in this show.

hmm.. i think this is the most plausible explanation for me..
still.. i don't get why he has to appear..?
i mean, i'm sure that parkman would have been able to find angela on his own..
with or without his 'appearance.'
that's all i'm saying..

I think the real question is Why Not Have Him In An Episode?
