As another reviewer has pointed out, this episode has two plot lines that don't seem to mix very well. The part of Captain Sheridan finding a dead alien and then starting to have visions for no reason that the doctor is able to find - this might work as an episode of some other SF series, but here it just seems minor filler. Except with this series you never know when some minor thing, some tossed off incident, is going to have repercussions and show up way down the line.
Thus if one is working through the series episode by episode, you can't help wondering about this, but only time and future episodes will tell.
As for the second plot line, an old friend of Londo's comes asking for help. This part has good acting, more complications for Londo and his quest to revive the Centauri Empire, and while he finally manages to save his friend's family, the cost is rather high. It's a moving story, and one feels sympathy for Londo at the end.
