It can only mean two things in my eyes: Either it's Daniel or it's Dylan who leave... and since Dylan is probably the really "impossible" thing and I think Jeff wouldn't have the balls to do so, it might be Daniel... which would crush my heart... Good thing I'll get to hug him in person...

I just read this second that Daniel is filming a movie, though, so maybe he just won't be there in the beginning of Season 4, much liek Hoechlin at the beginning of 3B when HE was filming a movie?

That's the hope I'm clinging to right now even if it's probably false hope!
