Late night ramblings...

so I'm watching Catching Fire for the umpteenth time. And I am wondering. What if a district doesn't have a mentor? Like in District 12, it's Haymitch. He is the only victor the district has ever had. What would have happened if he died? Like from alcohol poisoning? Who would have mentored Katniss and Peeta? What about other districts that rarely if ever had a victor? So there is my I can't sleep and my mind works in very strange ways thought of the night!
