What happened to calvin jr. on house of payne?

I didnt get to see the beginning of the episode of house of payne where Calvin jr. was in the hospital. I just got to the end of it where cj, janine, calvin, curtis, ella, tracy, and her man was all at the hospital. My friend told me that Calvin jr. was burned & idk if its true. Can somebody tell me what happened because i want to know.
