<P> The bartender and owner of the only Fae pub in town, the Dal Riata (aka "The Dal"), which is neutral ground where Light and Dark Fae can freely socialize and find sanctuary . Trick is very powerful: he is a Blood Sage and can alter fate by writing it with his blood . Once known as the Blood King, he forced the truce and wrote the decrees that ended the war between Light and Dark Fae; and though few are now aware of his former position in the Fae hierarchy, he is on equal terms with the Fae Elders . Compared to other Fae, who have contempt for humans, he is tolerant and often fond of humans, even trading away his most prized possession to help save Kenzi's life after she was infected with a lethal Fae virus . He respects Lauren and when necessary seeks her opinion and expertise with matters involving Fae . Trick is extremely reluctant to use his blood powers as it can have unforeseen consequences; for example, his writing a culmination where Aife's maternal instincts emerge and stop her from hurting and killing Bo not only left him weakened and wounded from the loss of blood, but also signaled his whereabouts to an ancient enemy of the Fae, the Garuda . Near the end of the second season, it was revealed that Trick is Bo's maternal grandfather . </P> <P> A Siren and Dyson's colleague as another Light Fae undercover agent in the human police force . He can pacify, control, and kill humans and Fae alike with his whistling; in addition, he can cure pain and heal wounds with it . He is the son of the leader of one of the three most powerful Light Fae clans, the Clan Zamora, but despite his family's high social status he disdains their social contacts and makes his own way in life (although Bo and Kenzi used his contacts when they needed to infiltrate a high - class Fae event). Hale is good friends with Kenzi, with an undercurrent of mutual attraction gradually developing between them . He helped save Kenzi's life by using his siren's whistle to cauterize her wound in the Season Two finale . In the third season, he became the acting Ash after Lachlan's death . </P> <P> A Valkyrie and Dark Fae bounty hunter introduced in Season 3 . She creates doubt and intimidation in her victims, can awaken a comatose person, senses from a cadaver the fear someone experienced before death, kills with mental power, and reincarnates into several life cycles until the last one . In "SubterrFaenean", Tamsin was sent by The Morrigan and Hale (as acting Ash) to work together with Dyson in a Fae clan exchange program . Their mission was to solve the murder of a Dark Fae that was drained of his chi outside the Dal Riata . At first determined to find Bo responsible, Tamsin becomes friendly towards her and defies The Morrigan . However, she had secretly accepted a contract by The Wanderer to find Bo and bring her to him . To capture her, Tamsin procured one hair from someone Bo loved (Lauren), two from someone she trusted (Dyson), and three from Bo's own head, and mixed them in a rune glass to create a special elixir that, when Tamsin threw the vial at Bo's feet and it shattered, the liquid marked Bo so that she could be "collected" by The Wanderer's agents and transported through transcending planes . Tamsin seduces Dyson in "End Of A Line" when he becomes low - spirited about Bo's questionable relationship with Rainer . As time passes, Tamsin becomes Bo's roommate in Season 5 and falls in love with her . In "It's Your Lucky Fae", she offers herself sexually to Bo as a birthday gift and Bo accepts her . However, later in "Here Comes the Night", when Tamsin tells Bo that she knows Bo's heart lies with her and that she is in love with her, Bo tells Tamsin that she did care about her and loved her, but "not like that". </P>

When does dyson and bo get back together
