The question seemed to originate from a fictional story, so the answer could only be based on fictional plots. But if this was a plot of a novel, then Morbosson might have made some speech at Flaubert's funeral to express his respect and gratitude to Flaubert and discuss the novel they had written together. Mobsang might say something like this: Flaubert, you are my greatest. I am grateful for all the contributions you have made in the field of literature. Your novel is not only a masterpiece of literature, but also a treasure trove of human thoughts and emotions. I am deeply saddened by your passing, but I believe that our literature will continue to flourish and inherit your spirit and wisdom. He might show some of Flaubert's works to express his appreciation for his literary talent and emphasize how much honor and achievement their literary cooperation had brought them. Other than that, Mobsang might make other speeches or actions to express his respect and gratitude, but these all depended on the details of the plot.
