Deja Brew — Mardi Ballou

Though Lisa's workaholism is undermining her relationship with Jack Ryan, she can't let up. Not now when she's this close to clinching the deal to sell Déjà Brew, a risky potion that transports customers to key moments of their past, through Jack's family company.

Jack's skeptical but willing to try -- even going so far as to sample the potion. He has a great visit to the past, reliving the first time he and Lisa made love. He comes back happy and ready to commit. However, Lisa's trip ends up traumatic -- and Jack immediately rethinks the deal.

But Lisa isn't giving up and persuades him to try the brew again. Together, they return to a romantic time in their past, which quickly goes south -- the night they agreed to let a friend film them making love, the night their relationship problems began. They got through the pain once -- but it's not at all clear they can do so again.
