"Survivors" fills an important part of Kimble's life that has been missing to this point in the series. His in-laws, while harboring hatred for him, are nevertheless sympathetic with his plight. His sister-in-law's infatuation with Kimble is an intersting and poignant touch. The writing is tight and tension remains high throughout the episode. The search of the in-laws' house will keep you on the edge of your seat. When Kimble is dropped off by his father-in-law at the end, their interaction and respect for each other seems to hint that he knows the truth of what happened. I rank "Survivors" amongst the best episodes of the series.
