* DawsonCasting:
** 36-year old Anna Silk reputedly lied about her age to get the part as 28-year old Bo.
** PlayingGertrude: Inga Cadranel, who played Saskia/Aiofe, a/k/a Bo's biological mother, is four years ''younger'' than Silk.

* HeyItsThatGuy:
** Two regulars from ''Series/{{Warehouse 13}}'' have had roles: Aaron Ashmore has a recurring role as Kenzi's boyfriend Nate and Genelle Williams is one of the Serkets in "Table for Fae."
** [[{{Series/Endgame}} Balagan]] apparently cured his agoraphobia to become a scientist/admirer of Lauren's scientific work.
** Looks like [[{{Series/Degrassi}} Jake Martin]] has become an at-risk youth.
** [[{{Series/The L Word}} Jenny Schecter]] is apparently an elemental.
** [[FarCry3 Vaas]] is apparently best buds with Kenzi.
** Series/OrphanBlack fans will spot Inga Cadranel (Detective [=DeAngelis=]), Daniel Kash (Tomas) and Michael Mando (Vic) in the first season alone - along with OB co-creator John Fawcett, who directed several episodes. Which may also explain Clone Club's collective {{Nerdgasm}} when Ksenia Solo joined the cast in Season 3.
