Looking back at the television show on TLC, "Lost in Transition," I think enough time has passed not to have to issue a "spoiler alert."
I think the producers did a fairly decent job of tying up many of the loose ends which occur when long term couples split up from transgender issues...or don't. Two couples on the show were very much on the relationship ropes and two weren't.
What was nice was all of the trans women managed make-overs somehow and appeared presentable. Especially the one from rural Washington State who was going to attempt to move her family to Wisconsin to look for a suitable job.
Of particular interest to me through out the entire series was the couple from California. Not only did the wife have many of the similar ideas of going into a transgender relationship that my deceased wife had, they even shared the same name. The back and forth between the couple continued full force until the end. I think once both of them saw the trans woman after a quality makeover, they knew they could never go back.
It was like another of the transgender women said, "I finally saw my true self in the mirror."
Then, there was the "go to hell" breakup with the couple from Ohio. Which could have been the most truthful of the four.
All in all, I think the producers of the show tried and succeeded in covering quite a bit of complicated ground in a short period of time.
Maybe the show will be "extended" into next season.
