meh. it was an ok scene. everyone knew about that theory and it was pretty anti-climatic for me. whats worse is that they didnt even confirm his father's identity.
If you mean everyone posting in the GoT threads? Yeah, but that's mostly thanks to books theories leaking over here and all around online but that blindsides the hell out of people. And they did confirm who his father was, the thing is, since most people didn't know the theory and didn't remember all the details, they really weren't sure who the father was but if you knew the theory, then that scene confirmed it.
