@Monkey:
So you're implying that Athrun is some kind of spy ? Since the ones who he's talking to seems to be against the Demon King. Saying things like : "for now, let's go along with the lord of fly's little farce". About the other guy being Beel older brother, it's possible, but it would be kind of strange for him to say something like : "you should expect nothing less from the royal lineage" if he's from the same lineage.
No its seems like he is proud and taking note of that royal bloodline, which also is an ego booster for himself, though Tamaura can't be too obvious with this kind of statement without revealing if he is or isn't related.
The fact he's praised it makes me think he has a close tie of some sort, be it henchmen, bloodline or another contractor similar to Saotome.
As for Athrun i cant call him a spy or against the Royalty if he saved Beels life. He most likely serves another in the family as Jabberwock does.
it would explain both the fact he saved them yet acted reluctantly to show any other kindness or introduction.
Yeah I think that too. The demon king has choose his two youngest king. It's like a way for him to make his sons grow up.
But the demon lord does everything on a whim, though i doubt he would send a baby and kid unless he didn't have many other options. Plus i doubt he would send a them both for any kind of growth or training…he doesn't seem to care or acknowledge that aspect of things. Or not to the degree you would expect of a father.
In short i think Athruns role is pretty obvious, while the other could be one of several people that are very familiar with the royal family.
