question about BSG

A question for the Battlestar fans on my flist.  I'm watching episode 3x09, because I think the episode 3x08, with the lost and angry pilot, is where I last watched. 

But the flashback sequence opens with Kara/Lee nasty stuff and I... don't remember that? I had thought I'd seen all the episodes in order, until this point. But I don't remember when this bit happened, or the context.
