if I understand it correctly, the words the empress said in the novel should be, " it's because of that behavior of yours that the rude (?) mercenary won't ever be loyal to me." when talking about Sir Johanne.
by saying how kind and selfless Jesse is, that even though the Solar Halo caused harm on him before when Sir Johanne tried to assassinate him by using it, he still wanted to grow it inside the palace for the sake of Gerrit, Sir Johanne's son. the Empress expresses that Sir Johanne's 100% loyalty will not be given to her but to Jesse instead. ಥ‿ಥ
Evelyn, you're gonna bore holes on Losna's face just by talking to Oliver
