Atticus tells the children that Aunt Alexandra has decided (and convinced Atticus) it would be best for the family if she stays with them for "a while," which worries Scout even though she knows there's nothing to be done. No, Scout doesn't believe that Atticus feels this but she does later understand Atticus's need to have his sister involved in their lives.
In Book 12, Ulysses is warned by Circe about the impending dangers of Scylla and Charybdis. She tells him not to harm the cattle of the sun god, Sol. Hope this helps!
