Ok guys! I’ve realized something!
Remember the 4x06 episode of TVD? While Shane is talking about Silas, there is a slide show behind him.
One of the images is a pic of the stone from the Silas’ tomb. It shows how the stone has a message written on it. And next to it there is an alphabet.
I’ve translated the message and it’s written in latin…
SILAS PRODITOTI DAMPNABER
Which means…
SILAS DAMN TRAITOR
Then… IS SILAS A TRAITOR??
Maybe he isn’t in that tomb!
