Lost Girl 4.03 (Sunday, Nov. 24): Bo jeopardizes her life to save a haunted family. Meanwhile, Dyson races to be by Bo’s side and Lauren’s past catches up with her. [ETA: This episode guest-stars Mia Kirshner (L Word, Vampire Diaries, Defiance), Ali Liebert (Bomb Girls), Chloe Rose (Degrassi; thanks to
rawr_santi for the info!), and a few other people whose names I don't know. If you happen to know who they are feel free to make a comment!][And just so people know, this is for the initial Canadian airing on Showcase; other channels haven't aired this season yet.]
(It looks like this still was mislabeled as 4.02, since I don't recall seeing this outfit/shot in 4.02 at all)

An extra still from 4.02 that amused me - Lost Girl: The Musical
There's another extra/new still from that scene @ source 6, but I think at this point we've seen more than enough shots from that portion of the episode.
