The Next day Arc was allowed to come back to his nation without any mishap.
But he was furious when he heard that Arman was made the temporary overseer of the network. He has doubts about Arman from the start and he also met Nicholas when he was in the Thunder god temple and learned a thing or two about him.
Whatever there is between Sam and Arman, it is definitely not friendship.
He still didn't tell them about Sam and his friends being back, he went to meet them completely cursing the stupidity of the officials to appoint Arman this illogically.
But he felt that Arman seemed to have some serious glib tongue to gain this favour from various factions.
He was thinking on how this guy visited each and every faction and might have even used all kinds of cards, including his 'friendship' with Sam, his authority in the thunder god temple and so on, to fool the executives.
