Given the ending, it should be, Episode 5: "Back off Cindy, or I'll drain you..."
I replayed the fight scene again and chose to fight Marcius and lost a potential power, the funny part of it was, why didn't MC just turn himself invisible and carve Marcius up instead of the weird "out of body experience"? It would have sent a clear message to the court that MC & Sharon weren't to be fucked with! Mind you the fight probably did do that... Come to think of it why didn't MC use that in the tunnels against the ancient? Did the devs forget that they gave MC that power??? Come to thinks of it, did he have that power back at the pool fight already?
