-As dry electrical storms prevail in Haven there is growing concern about the changing climate. Noah devises a plan to harness the lightning, which strokes most often on Razorback Ridge, and so powers his PH-Ts. Monsoon wins back favour in the Nomads' compound by bringing in a wounded animal and half of a weathered amulet. Kwan produces the other half, given to him by his long-lost mother. With the prospect of reuniting with her, Kwan bids the Nomads farewell. Though his hopes are dashed, a heart-broken Kwan has too much pride to return to the compound. Monsoon, meanwhile is spooked by a visit to the family. It seems these people can communicate with each other telepathically. Up on Razorback Ridge, Arushka insists Noah test the PH-Ts before using them on himself. The stand-in scarecrow is burnt to cinders as lightening is channelled into the PH-Ts. Nevertheless Noah ignores all protests, reconfigures the equipment and successfully time-travels back to North Col. Noah's family are relieved to see him but the North Col authorities thrust him into the detention centre for breaking the time travel ban. Myah is lurking in the North Col sludge pipes. How and why has she accompanied Noah on his time travels? (thetvdb.com)
