The monster’s pretty smart though, and he changes tactics by saying that Victor owes him a mate. It is his duty as creator. (Think God, Adam, and Eve.) He says it will make him less evil because it is loneliness that has made him such a grumpy jerk/murderer.
The monster promises to take his new mate to a South American jungle and hide away from people for the rest of their lives. Sounds fair.
Victor bends like a wet noodle. He agrees, convinced by the monster’s smooth rhetoric. The monster is thrilled. He’s going to have his own girlfriend.
Still, he doesn’t exactly trust Victor-the-Dead-Beat-Dad. So he vows to follow Victor to check in on his progress. He says he’ll know when the work is done, which is just a little creepy and ominous.
