I have already made a theory on who and why I think that person is RJ

The thing I'm more curiose on now is how the meeting will come together, we know that the final between them will occure in a park, just the two of them alone, that RJ will expose himself to Patrick, but do we know how he will do it, ?

Will he just call him, and ask for a meeting ?
