Svari is a child
And a Babette
You can tell her about the Dragon that attacked you in Helgen. This makes Svari very excited.
She also tells you that her mother, Greta, no longer goes to the temple. If you offer to help convince her, it will start a quest called "Return to Grace" where you have to return Roggvir's Amulet of Talos to Greta.
You can also give Svari a gold coin, and receive a blessing: The Gift of Charity
