Sibling Rivalry-1.png

This quest will begin after the fledgling has taken care of the hitmen in the Surfside Diner during the Bad Blood quest. Either Jeanette or Therese will call the fledgling on the phone at the back of the diner, to explain that she has locked herself in the bathroom under threat from her sister.

Race back over to The Asylum and take the elevator to the second floor. The fledgling will walk in to find out that Therese and Jeanette are one and the same, something that is hinted at if the fledgling is Malkavian. The two are lost in a heated argument, revealing dark secrets about their past while the fledgling interjects occasionally, swaying the fight one way or the other.

There are three different scenarios that can occur here.

  • Side with Jeanette for Experience Rewarded (Icon).png 1 point of experience.
  • Side with Therese for Experience Rewarded (Icon).png 1 point of experience.
  • Convince them to coexist for Experience Rewarded (Icon).png 3 points of experience, Humanity Gain (Icon).png Humanity Gain, and either a Revolver .38 or its respective ammunition. (requires four ranks in Persuasion, and to have a good relationship with both, explained in more detail further below)

Regardless of the spat's outcome, the quest will be completed and the fledgling will be given the opportunity to meet with Bertram Tung within an old oil tank at the SunCo Gasoline facility just down the street.

Relationship with Jeanette and Therese

Whether the Voerman sisters can be convinced to coexist is highly dependent on the relationship the fledgling has with both sisters. For the necessary dialogue options to appear the fledgling not only requires Persuasion level 4 but also has to be in equally good standing with both sisters, the relationship is influenced by each dialogue option chosen throughout each conversation with either sister since Jeanette's introduction at the Asylum.


The relationship status for each sister is stored in a separate variable, G.Therese_Seduce and G.Jeanette_Seduce. The default values of both variables are 0 and are influenced via the dialogue choices made during each conversation with either sister. Seductive or flattering answers increase the corresponding variable, insults or offensive suggestions reduce it and neutral answers have no impact. In the original game each value needs to be both at least 4 and equal to the other. In Unofficial Patch Plus both values need to be equal to or larger than 4 but do not have to be equal to each other.
