I agree with you I think he is testing her but I think he's going to underestimate her and she's going to do something that impressed him but with him not knowing that he was the one who trained her in an alternate reality I can actually see them becoming business partners
I think after she's done establishing a partnership with the Merchant company I think she's going to visit the kingdom that she was protect them when she was a knight and established a diplomatic treaty with that Kingdom as well
From my understanding it seems like the future is always set in stone with minor differences with Rishe and with her keeping all of the skills that she learned from the alternate realities I think things are going to play itself out a little different with her making allies with each and every one of the people from the other realities as well

It feels like he's testing her. Or you know, like what she said, he's already seen through her intentions.
Well. She has to remind herself that this is a timeline where they don't know each other. She might be misled by her impressions of him when she was in the trading company.
