I canât believe I havenât seen this take before, but Loid wanting to replace Yor for the mission is EXACTLY proof he is starting do develop feelings for her beyond the mission.
Think about how hard it would be to replace Yor with Fiona at this point, not to mention there is a risk of Anya not wanting to go to school anymore. Going forward with Yor is the safest bet, however, he wants to replace Yor because unconsciously he is becoming uncomfortable with the prospect of using her.
Think of how much the mission matters to him and then think about how he is risking it all for her.
