I agree with you.. At first I thought that the kiss was the teaser for the episode to illustrate the type of relationship that Donna thinks needs to be defined later in the episode. But the part where she says "who said anything about talking" really doesnt fit unless it is after the ultimatum IMO.. so I agree with you, I think it is after California! I am soo giddy about getting another kiss cause the kiss in "The Cold" was better IMO then all the sex we have gotten..it was just soo hot!
