Plot summary
After remembering Bo, Dyson revisits the crash site and finds a small girl who is Tamsin reincarnated. She has no memories of what happened, but Dyson and Trick leave her under Kenzi's watch in case she remembers something useful. Meanwhile, Dyson and Hale track down an elemental fae who may be able to find Bo. Tamsin however, finds the tarot card in a box of Trick's things that turns out to be a train ticket to the train Bo is on. Dyson takes the ticket and attempts to board the train, which is a death train, with the help of Clio, an elemental who keeps popping up at exactly the right moment. During this, Hale confesses his feelings to Kenzi, who admits she feels the same way and the two passionately kiss. The scene ends with Bo finally escaping the train, unaware that Dyson is trying to find her.
