Orphan Black 2.9

Allison & Donnie probably have the best storyline here (particularly Donnie). Everything else has a sense of covering old ground: Helena is back with Henrik Johanssen (again), Rachel is scheming to get Kira (again), Vic is working undercover for Detective Angela (again) etc. Show seems to have taken step backwards from the high point of midseason. Have we really advanced very far this season? 8/10
