The best way to summarize the theme being discussed is The character of Penelope is very loyal.
Explanation:
This excerpt from a discussion of themes in The Odyssey only gives information about Penepole being loyal it doesn't say anything about the kind of relationship she has with Odysseus, either if they have known each other for a long time or in general terms any kind of specific information about the relationship besides that precise moment when she showed to be loyal.
