Lost Girl - Episode Guide

In the series opener, Bo's impulsive decision to protect a young woman in jeopardy (Kenzi) has unexpected consequences: the two become fast friends, while Bo is swept up into the secret world of the Fae, learning for the first time about these ancient people and the birthright she never knew existed.

Fresh from the realization that she is a member of the Fae, Bo is approached by a strange client, Will, a real life Will O' the Wisp. The storehouse of jewels he's collected over the centuries has been stolen...by a human! While this line of work is foreign to Bo, Will offers her an irresistible payment - information about where she might have come from. As Bo gets involved in the recovery of Will's gems, she finds the shocking truth about the thief... and the weird and deadly forces that seem to also be on the trail of the jewels.

When a missing coed's mother comes begging for help, Bo and Kenzi go undercover on the local college campus to find her. Using all of Bo's unique talents and Kenzi's con artist skills, the women dig into the mysterious underbelly of the school's sorority system and find a surprising Fae connection, while racing to save the kidnapped young coed.

On the personal side, Bo and Dyson enjoy the afterglow of their first sexual encounter, both wondering where it's leading them... until Trick's stern objections and Kenzi's excited pressuring threatens to put a rift between Bo and Dyson before they're even a couple.

When a Fury with an unfaithful spouse tries to hire Bo to kill her husband's mistress, Bo instead takes the side of the unsuspecting human woman and puts her under protection. Things quickly spin out of control, however, after the husband ends up brutally murdered, leaving Bo scrambling to contain a mess of jealousy and violence and unravel the mystery of the real killer – as Kenzi nearly becomes the next victim.

Dyson has to submit to therapy at the cop shop when his romantic frustration over Bo causes anger issues, leading him and Bo to patch things up.

Bo is coerced into solving how a human scammed Mayer, a Dark Fae bookie. Things get creepy when she discovers the con artist behind it all is a Hsien, a Fae that can inhabit dead human corpses.

Kenzi's determination to prove she's more than just the human "sidekick" leads her to do a little investigating on her own, which lands her in some serious hot water – and eventually, locked in the trunk of a car headed to a bad fate unless she can be rescued by Dyson.

While tagging after Lauren and Bo in the Fae world, Kenzi becomes deathly ill (and incredibly grossed-out) when she inadvertently eats some toxic human soup at the home of an Aswang - sending Bo and Lauren on a daring undercover mission in search of a cure, at a powerful pharmaceutical company.

As Bo and Lauren race to save Kenzi, they are each forced to face their varying control issues – with surprising results – underscoring their growing attraction and the beginning of a possible relationship.

When con artist Kenzi runs a "Shaman" scam, and does a spiritual cleanse of a human house where a bloody murder-suicide took place, she inadvertently brings home a vicious Fae spider whose venom turns people psychotic. After getting bitten by this nasty eight legger, both Bo and Kenzi's paranoia mounts – and the best friends begin to turn on each other in this haunted house homage, forcing romantic rivals Dyson and Lauren to put their differences aside and work together to find a way to kill the nasty arachnid... before Bo and Kenzi kill each other.

Bo's freelance work earns her a lead on someone who might know something about her mother... but the trail ends at Lou Ann, a death row inmate who claims not to know anything about Bo. Desperate to prove otherwise, and increasingly convinced Lou Ann is innocent; Bo uses all her political wiles to try and bust her out of jail. When she has to admit defeat, Bo's goal switches to one of personal vengeance: to find Vex, the Fae that framed Lou Ann, and make him pay.

A fun-filled Fae "high holiday" turns potentially deadly when a Banshee wail predicts the death of someone in Trick's bar to occur within the next 12 hours. After a scramble that puts Bo and Dyson on the Banshee's trail, the two learn the name of the Light Fae (Sean) who's marked for death – and his last wish is for them to help him reconcile with his Dark Fae brother. Bo has to heal the rift between the two brothers at great risk to herself, while trying to unravel and prevent the mysterious death omen hanging over Sean.

Amidst helping adorable Sean write a bucket list and make the best of his last day on earth, Kenzi unexpectedly develops feelings for him... and is unwilling to give him up without a fight.

While investigating a baffling sex-related murder case, Bo comes into contact with Saskia, a strong, sensuous Succubus who has much to teach her. The two become fast friends, but as they work together to solve the case Saskia reveals her true dark Fae colours, which tests the limits of this newfound friendship... and Bo's own inner bad girl.

Kenzi – feeling a bit left out due to Bo's new gal pal – joins forces with Trick in a race against time to save The Dal Riata.

When Dyson wakes up bloody and without the last eight hours of memory, he finds himself accused of murdering Ba'al, a close associate of The Morrigan's pet psychopath, Vex, and takes refuge in Trick's bar, invoking sanctuary. It's up to Bo and Kenzi to recreate Dyson's lost hours and to find the real killer before the forces of the Fae, both light and dark, join forces to take Dyson's head. If Trick tries to prevent it, there may be more blood spilled... and an all-out war amongst the Fae might ensue. In the end, Bo and Kenzi fight to find the truth amid a morass of old hostilities and twisted loves... and get the proof to Dyson in time to save his life.

Bo and Dyson go undercover as a married power couple at a swank country club to help an old friend from Kenzi's criminal past. At first they enjoy their taste of the good life – and the chance to play house. But soon the emotional pressure of the charade, and the increasing body count, push Dyson and Bo to a new level in their relationship...and prompts Dyson to give Trick an ultimatum. It's time for them to tell Bo all they know about her origins once and for all. But before Dyson has a chance to come clean to Bo, an unexpected arrival drops by and tries to silence him for good.

Bo has finally learned the truth about her mother – and that those closest to her have been keeping secrets about her past. Reeling, no longer sure who to trust, Bo decides to track down "Mommy Dearest" alone, in order to extract the truth about her own origins once and for all. While everyone frantically searches for Bo, Dyson visits an ancient Norn, a wish-granting, tree-dwelling crone, where – in order to protect the woman he loves - he makes a sacrifice that may irrevocably change his relationship with Bo forever. All these paths converge in a final face-off between mother and daughter that forces Bo to choose who will be saved…and who will not.

In the season opener, a nomadic Fae sideshow comes to town looking to take advantage of the chaos that the bombing of the Light Fae headquarters has wrought. Unbeknownst to the general Light Fae populace, The Ash is in a coma, and his bond with the land is weakening – which makes this the perfect time for the travelling circus freaks to steal the most precious thing the Light Fae possess.

The hunt for The new Ash is on. Literally. A traditional Stag Hunt is held, whereby the candidate who successfully tracks and kills The Stag becomes The next Ash.

The Morrigan enlists Bo's help to find a tortured graffiti artist under her employ.
