Having precog abilities didn't guarantee having answers, but it did mean Walker knew when trouble was in a specific area. In this case it was Finland and involved someone associated with Levi and a friend to Walker. So he wants in on this job - even if Levi doesn't have a job there. Yet. However, a quick phone call to Terk confirms Walker's suspicions. And he's already on the move.
Ashley's life should have eased up with her move to Finland, but that same wariness creeping back in her life made her feel hunted once again. A strong healer, she helped those who showed up on her doorstep, telling them that she believed the healing energy brought them to her.
