Bob continues to be haunted by memories of his time at Roth's secret lab; Wes insists that Rachel inject him with a highly experimental decoy drug composed of mutant red blood cells to fight the virulent Hep C; a mysterious disease that's causing brain inflammation in a small town appears to be contagious.
Misleading title. I had to think after the episode was over, what was "the kiss". Of course it refers to the dog kisses, but I was concerned more with the Mayko/Bob kiss, the mystery woman/ Bob kiss, and also the Wes/Rachel kiss.
Is there any possibility that Wes could have spread Hep C to Rachel? Didn't they hook up after he got scratched??
