Understanding Clara's Conflict in Dialogue

In modern drama, the use of dialogue can reveal a character's intentions and layers of meaning beneath their spoken words. Consider the following excerpt from a fictional play where a character named Clara is conversing with her friend, Mark.

CLARA: *I just don't understand why you would choose that path.*

MARK: *Sometimes the choices we make are not for others to understand.*

CLARA: *But we’ve always walked this road together. Why go down a different one now?*

MARK: *This is my journey, Clara. You have to let me be myself.*

In this exchange, the dialogue serves to highlight key elements of conflict and emotional depth. Based on this dialogue, what does Clara's response primarily reveal about her character?
