I haven't decided what I think of the Bo/Tamsin pairing, but overall as a character I think Tamsin is pretty cool. I've especially liked what they've done with her over the last few episodes, as she started feeling more conflicted about what she's supposed to do to Bo.
Oh, and I didn't notice if anyone commented on the return of Aife. I thought that was pretty surprising reveal that I did not expect at all.
More importantly... where did she go after she offed the bartender's wife? Is she going to rescue Bo, or is she returning to her husband? She looked suspiciously involved with the bad side in the end.
Wonder who's going to take care of the cabot's (?) 36 children after Aife succukissed her?
