Instead of capturing Carmen, the Faculty managed to kidnap Shadowsan, taking him back to the island and keeping him there for a long time. Neither you or the rest of the red team knew what happened to him, untill the night where Player found him. Shadowsan, stealing from a museum of London, there was no doubt, he had been brainwashed by V.I.L.E

What neither of you expect, was to find him in the same mission in Japan. Shadowsan was sent to capture Carmen, but found you instead of her, but that didn't change anything, you were part of her team, it was enough for him. He didn't hesitate to attack you, ignoring your attempts to talk to him

"Unless you take me to Carmen... I'll have no mercy with you..."
