Sergei Schevchenko

Sergei Schevchenko is a potential victim of Dexter Morgan in Dexter: The Game.

History
Sergei first appears at his house, drunkenly rambling nonsense, when Xandro Lopez suddenly pulls into his driveway, upset about something the player can't hear over Dexter's talking and Sergei's drunken rambling. Dexter takes the time while they argue to investigate Sergei's car to find evidence of Robert Marelli's murder.

After Dexter hides behind some bushes, Sergei tells Xandro he can't bring Robert back from the dead, and Xandro is upset that they have to find a new meth cook. He warns Sergei that if he loses any more money, he'll kill him. Sergei tells him that he has the money to pay him back and invites him inside his house. Dexter (the player) than has a choice to make: either kill Sergei based on the information he already has or start investigating Xandro instead.

Kill Sergei
If the player chooses to kill Sergei, Dexter sneaks into his house when Xandro leaves, and after Sergei passes out drunk, Dexter sets up a kill room and murders him with either a knife, an electric saw, or a meat cleaver, depending on the player's choice. Dexter then dumps his body into the ocean and puts his blood slide in his blood slide box when he gets back to his apartment.

Since Sergei wasn't the one who killed Robert, Sergei is one of the few people Dexter kills who was innocent of the crime he thought they had committed.

Spare Sergei
If Sergei is spared by Dexter, he is never seen or heard from again, but it can be assumed he got away with his crimes, unless he somehow managed to get himself arrested.
