Narrative - plan b
While they would try their best with Rachel to see what they could do to retrieve the others, Hank had to start on plan B, just incase it was needed. Forge wasn't available to help him on site, but he'd taken the time to get in contact with the mechanical genius for a few suggestions. With that, Hank went to work on one of the many time jumping bands that had been left behind. He wanted to work out any thing that might interfere with their safe return - like Lorna said, a magnetic disturbance could screw everything up. It would take a day or two for him to get everything straight - he'd make a point of asking Kitty for her help.
