Alex:
You are aware of Sonin and Pano's troubles? I also need help. If you assist me, I am willing to write a letter of reference for you.
I am sure that Sonin and Pano will do likewise if you help them, too.
Ask about Warehouse Keeper Sonin's problem. Ask about Grocer Pano's problem. Ask about Alex's problem. Tell him that you are leaving now to resolve the problems.
