Just watched 'Tapestry' and I don't understand how Jean-Luc survived at the end? He decided to fight knowing that he'll get stabbed through his back and will need an artifical heart, and we were told near the beginning of the episode by Q that the artificial heart would lead to him dying 30 years later because Beverly wouldn't be able to rescue his artificial heart, but somehow he survived? What happened? The only thing I could come up with is that maybe the Nausicaan missed his heart this time, is that what happened?
I enjoyed the episode, I just didn't understand the ending.
