Wow. I thought this was one of the best episodes of the series so far. I haven't been this impressed with a Michael Taylor script since DS9. The political maneuvering by the Tarrs was very deft and thorough (though it's a bit contrived in that they had no way to be sure Nolan would be the one to spot/shoot the "assassin," rather than Irisa or Tommy doing it, or nobody stopping him before he fired). And we finally get some answers about Irisa that are more interesting than another oogy-boogy mystical Chosen One cliche and that tie her arc into the larger seasonal arc.
