Bob searched the internet about what has happened to them and interestingly enough, he has found that there is a potion that can be used to reverse the effects from a shifty website offering magical potions. It will take a week before the potion is delivered to them but Bob still pressed the order button anyways as he did not have much of an option. He also saw a footnote in the website saying that both of them must avoid engaging in sexual activities (including masturbation) as that will make their minds confused in the bodies that they are in. Since Bob assumes that Lucy wont be having sex nor willingly be masturbating anytime soon, he doesn't worry about it that much.
Upon doing so, he talked with Lucy, now staring in the mirror more seemingly confused while at the same time admiring her new body, on how they will settle in before the potion arrives. Lucy has to go to his father's job while Bob needs to go to school while they are in each others body, and that idea worries them as they know nothing about how each others lives go.
