"Come, take the leaf..." The princess said again as Aldric fell silent.
The latter hesitated somewhat.
"Your Highness, you will lose if it is given to me," he said.
If they were indeed working together, various results were natural.
However, here he was helping because he was being paid by her with real money.
"All I need is one, having two is also meaningless and I am too rich to sell treasures. If you use that leaf, it's more useful. You'll progress faster, which means I can keep asking for your help later," the princess replied.
She gave him a reasonable reason why he should accept the leaf, but he thought this was still unreasonable.
Couldn't the princess give it to her family, Prince Charles for example. However, she preferred him.
Unless she really thought only he could continue to help her because the others were not talented enough.
