I don't know exactly,but I think it's fake, because I observed and noticed that neither Jensen nor Jared have this tatoo. As I know their bodies are clean from tatoos.
They are fake... Actors won't get tattoo's for a show...Also correct me if I'm wrong but they only show their tattoo once right? If you saw it every show they would have to put that temporary tatt on everytime and that would just be extremely exspensive and harm the skin after so long I hoped I answered the question lol
at least two times together, plus i know you can see it on sam in bed in "free to be you and me" as well. so more than once, but yes definitely not every episode
I dont know about it.
But possesions by demon is real ,i have seen myself in parbat,Nepal.When this demon posses people of this area it ask something for exchange.I dont you will beleive it or not but possesion thing is real.
not sure about tatto though
