We all know what happens with Soma in AoS, but what about Arikado/Alucard. We only see him three times during the game:
(1) at the beginning in the entrance when he protects Soma and Mina for the most part from enemies using his soul steal spell. After which, he says that he will put up a protective barrier to protect Mina.
(2) in the underground reservoir, just after Graham stabs Yoko. At which point, he says that he will see to her injuries.
(3) in the throne room, after the battle with Graham (assuming you beat it the right way).
My question is: What was he up to in between those events? And how did he get to that room beyond the throne room?
