Now, go left to the leper colony. The storm drain gate is up left. Use the rung to get up there. The nice mister takes care of the children while you are up there. Go look at the drain gate. Take care the Middle Rufus is next to the storm drain in Porta Fisco. You can now drop the items from your inventory between the Left and Middle Rufuses. You don't have to stand next to the grate to do that.
