Where Can I Find "House" Season 3 For Free To Watch Without Downloading Anything?

I have searched all over the web to find a sight that had House episodes from other season. I can't find one without paying for each one then I have to download it. There are a lot of episodes I missed in season 3 and would like to spend the time to catch up. I didn't understand why House is hiring a new team? What happened to his old one and Why did he firer Foreman? Could you please tell me where I can get my answers from "House" season 3 without downloading or paying anything? Could you help?
