Γκέραλτ first meets the Novice nun (or Novice nurse) at Νοσοκομείο της Αγ. Λεμπιόντα. She tells him about the goddess Melitele and about sacrifices of fruits, plants or Λουλούδια on Melitele's altars. Sacrifices of Λουλούδια like tulips, orchids, roses, etc... are not acceptable. Only sacrifices of fruit like grapes, blueberries, raspberries, or dried fruit are worthy.
Later in Chapter II, if Γκέραλτ speaks with her again, he can ask a sort of cryptic question to which he gets an equally cryptic reply but it does not seem to impact gameplay in any way. Finally, in Chapter V, he finds her in the Safe house, along with Vaska, Golan Vivaldi, the hermit, the resolute girl and Vetala. They speak about whether or not Ithlinne's prophecy is coming true and she also gives him an update on Carmen and Vincent.
