An escape pod has crashed onto the planet below and the Enterprise investigates. The being inside is near death--yet, inexplicably, he survives. Not only that, but his body has amazing recuperative powers--and without this he never would have pulled through. Additionally, there is something about the guy that makes those around him really like him...including the Doctor. At the same time, the once shy Geordi suddenly is a hit with the ladies...all this following his being linked, briefly, with the alien. Who is he and how does he have such powers? When asked, this John Doe says that he has no idea who he is. Who is this being really and what sort of agenda does he have, if any? And, from whom was he escaping when they found him?
Apart from the annoying plot element where John couldn't remember anything until the very end of the show (and there was no explanation for this), this isn't a bad episode. On the other hand, almost all the episode was aboard the ship and the ending was a bit too 'nice' for my taste. Overall, watchable but weak.
