have they ever kiss?

Well...not yet. And honestly..? I don't think that they'll share a kiss soon (although I still secretly hope for it!xD). I think if they really get together at some point, it'll be مزید later than sooner. Probably there will be these Jisbon moments (what would we do without them??xD seriously??xD) and hints that lead to the possibility of a romantic relationship between them. But nothing really concrete. For a kiss? I guess it'll take them at least 2 مزید seasons. (I've read Simon Baker signed for 7 سے طرف کی now.)
