Where can I watch Supernaturals online? I found a site but it doesn't have "the kids are alright"

I want to watch the one from last Thursday, I think it was the 11th, but I can't find a place where I can. I checked the CW, but it wasn't there. Does anyone know where I can find a place to watch it FOR FREE ONLINE? I want to watch "The Kids Are Alright."
