Orphan Black - Season 4, Episode 04: From Instinct to Rational Control
It's back to basics for the cult show as the fourth season kicks off in lean, fresh and easier-to-follow fashion. Season 4 opens with Sarah's hard-won refuge in Iceland getting shattered by a Neolution attack...
"From Instinct to Rational Control" (and, indeed, the series as a whole) is a hard item to critique-after all, it's near impossible to properly judge rising action until you have the whole layout to judge it against.
It's possible, in fact, that M.K. tipped off Sarah to the imminent attack in Iceland in the first place in order to eventually lead them all to this endgame. Seems a stretch, but Orphan Black has pulled off stretchier.
