 TV Squad writer Jane Boursaw praised Olivia 's entrance in the episode , calling it a " Nice set @-@ up for the focal point of this episode ... Really nice storyline to heave us face @-@ first into the new season " . She lauded the Charlie @-@ shapeshifter plot twist , stating " The possibilities are endless with that storyline , and it 'll be fun to see how it all plays out " . SFScope columnist Sarah Stegall praised Joshua Jackson and Lance Reddick 's performances , giving Jackson " top honors " as he " once again shows us the fangs behind that cherubic smile " . Stegall also noted the allusions to The X @-@ Files , which included an episode playing during the first shapeshifter 's transformation , " Which is fine , as far as I 'm concerned . If I can 't have Mulder and Scully , I 'll take Walter and Peter , and even Astrid and Charlie ... I 'm happy to see another show on TV that deals with the unknowable and the possibly fascinating , with an actual budget in hand . If this show started out as X @-@ Files Light , it 's developing some serious weight now . "
