Another solid episode with drama and comedy in equal measure
6 February 2019 | by DVD_ConnoisseurSee all my reviews

There's a wonderful balance between suspenseful drama and light comedy in this episode.

Felix and Donnie pose as a couple to infiltrate the mysterious fertility clinic operation and Alison gives Donnie a helping hand when it comes to inspiration.

Meanwhile, we discover the tragic backstory of MK.

10 out of 10.
