Final answer:
Jonas feels confused and conflicted when he begins to have romantic feelings for Fiona since his society suppresses such emotions, and this is a new experience for him.
Step-by-step explanation:
When Jonas begins to have some romantic feelings for Fiona in Lois Lowry's 'The Giver', he experiences emotions that are quite complex and new to him. In Jonas's society, emotions and attachments are regulated, and having strong feelings like love or romance is generally unfamiliar and discouraged.
As he starts having these feelings, Jonas encounters internal conflict and confusion. This is because he is living in a community where such emotions are not commonplace and are suppressed by the use of medication to hinder strong emotions. His feelings for Fiona represent an awakening to the fuller spectrum of human emotion, which is part of his broader journey towards uncovering the truths of his community and the suppressed nature of human experiences.
