"Does she really have to?" Rudolph asked evident concern in his voice.
Austin shrugged, "Things would be easier with her here but if you are worried-"
"No, Austin. I will stay." Rhea told her decision.
After Austin told them the necessity of an archer near the Capital who could take down the draconic beasts, Rhea made the decision that she would stay here—a place where she was more needed.
Rudolph was worried, naturally, since if she had remained in his field of vision, Rudolph could have fought to the best of his ability. After all, until the ones he loves are safe, Rudolph can face the whole world.
However, asking her to stay with him just because of his worries wouldn't be childish. He should trust Rhea's skills and have faith that she can take care of herself.
"Can you give us a moment?" Rudolph asked and Austin readily nodded, "Sure, I will be waiting near the back entrance of the palace."
He soon sprinted away, leaving the duo alone.
