"If we can fix whatever Creighton and his friends did...maybe," Lena replied. "I'm sorry Jake, Hannah, I could lie to you and say I can fix this with the snap of my fingers but I don't think that would be showing either of you much respect. You two need to go back to Dallas, but you can't use that device," she said, pointing to the device on Jake's wrist.
"But it works fine," Jake said, an incredulous look on his face."
"It may well do," Lena said with a smile. "But that thing is gonna stand out a mile in the 1960s. You need slightly more hi-tech kit, the kind of stuff Project Unicorn uses. Plus, if Hannah's coming with you she'll need one too. That is, assuming she wouldn't rather stay here with me and let you have all the fun."
