Well that, and also the possibility of having offspring "out there" is terrifying. Especially if you don't know how they're doing. Open adoptions are another thing though, and there are situations where the biological parents are unfit, but yes, my squick buttons you push them.

Let me also add that I knew beforehand that Jon can feel Stephen have sex, be in love, be happy etc. and then you put it in and it kills me.

I honestly don't see how this can work out. If they get back to shore Jon will feel how happy and in love Stephen is and Stephen will feel how lonely and heart broken Jon is. I wonder if distance would break the link. :-/
