I liked the double-John act... obviously, you knew from the get-go that one was dead... after Talyn-John hooked up with Aeryn full-time you DEFINITELY knew he was dead, but still, managing to draw it out for most of an entire season isn't something most series would do... an episode or two parter sure, but most series don't have the creative capacity...
Yeah, it was ballsy. Interestingly though, Crichton was only split for about eight or nine episodes, but the repercussions from that lasted even until early season 4. I'm not sure many shows could pull 'that' off.
I guess kudos are in order for Browder for acting the part so well...
It's good too, that the writers managed to simultaneously not forget about it, but not let it dominate the story by incessantly calling back on it. It just managed to hang there, unspoken, like a pall, only occasionally mentioned, as a true tragedy should be.
