"Episode four of Orphan Black opens up a whole new chapter of creepy weirdness from its grisly opening scene onwards, as we delve deeper into the world of deranged clone killer Helena...  No longer able to go on the run with Beth&amp;#039;s cash and eager to learn more about the messed-up, self-harming blonde who&amp;#039;s been stalking her, Sarah (Tatiana Maslany) goes back under as Beth - and handily, her next investigation sees her looking into the murder of another of Helena&amp;#039;s victims... Some pretty nifty police work sees Art (Kevin Hanchard) and co. identify the numbers on the killer&amp;#039;s blood-spattered &amp;#039;fortune teller&amp;#039; as addresses, with only one remaining unvisited by the cops.  Unfortunately, while the cops - and Sarah - are out on the beat, Helena infiltrates the police station, staying just long enough to record an incriminating video &amp;#039;confession&amp;#039; in which &amp;#039;Beth&amp;#039; appears to admit to murdering Margaret Chen. That&amp;#039;s one smart psycho!  Backed into a corner, Sarah eventually agrees to meet with her warped double and learns that the late Maggie Chen may have been behind the whole clone fandango and was killed by the real Beth to protect her &amp;#039;sisters&amp;#039;. Art interrupts the confrontation, awkwardly finding Sarah alone in Chen&amp;#039;s apartment, robbing us of any more answers for now... How will Sarah talk her way out of this one? Stuck in a tight spot, she responds by handing in her badge and gun and quitting the force - walking out of the cop shop, apparently for good\u2026 This Week&amp;#039;s Big Questions...  - Helena&amp;#039;s motive is revealed this week - she&amp;#039;s an extremist who believes her clone sisters are abominations, the Devil&amp;#039;s children - but who has put her up to her murderous crusade? Is it the same behatted gent who rescues her at episode&amp;#039;s end? - Why exactly did Helena summon Paul to the police station? - Why was Alison so surprised that Kira was Sarah&amp;#039;s biological child? Alison&amp;#039;s only children are adopted - can the other clones not have children? - Art has plenty of questions about &amp;#039;Beth&amp;#039; fighting off the killer and why she &amp;#039;mistook&amp;#039; Helena for a man - is he close to uncovering the truth? - Paul (Dylan Bruce) and his tense face-off with Art... what&amp;#039;s the history between these two? Art looked even grouchier than ever when he found out that &amp;#039;Beth&amp;#039; and Paul were back on... - How did Kira immediately identify Alison as an impostor? Was it just that inimitable bond between mother and daughter... or something more? - Sarah&amp;#039;s recorded confession left for Art - that&amp;#039;s got to come back to haunt her, right? Orphan Black continues on Fridays at 9pm on BBC Three. "^^<http://www.w3.org/2001/XMLSchema#string>
