Barnabas and Julia are parents! Adam imprints on the first person he sees--Barnabas. But nothing could have prepared Barn and Julia for this large, clumsy, infantile creature. They notice that he seems to be very sensitive to their tones of voice, especially when they're arguing about him. They decide to sedate him, but he takes an instant dislike to both needles and Julia. Barnabas--who seems to have some kind of strange power over Adam--eventually persuades him to lie down and sleep.
It's only 5:00 a.m., and Barnabas is wondering if he's still a vampire when Elizabeth comes to the House by the Sea to ask Julia to examine the suddenly mute David. Barnabas frets about the time, but Julia assures him she can return in an hour. While Julia goes to get her medical bag, Elizabeth observes to Barnabas, You to have taken a sudden interest in science. That seems strange for one so fascinated with the past. Barnabas replies, I have no more interest in the past, only the future--the immediate future. Meanwhile, Adam explores Lang's lab, delighted with almost everything he sees though utterly ignorant of its purpose.
Julia returns to find Barnabas sitting in the dark, ready to die at sunrise rather than revert. Julia insists he won't die--and she turns out to be right. Barnabas rejoices in a particularly splendid sunrise, but he and Julia have little time to rejoice. Adam is attracted to a bright shiny scalpel and promptly cut his hand with it. Sobbing angrily in his first experience of pain, he has started wrecking the laboratory, smashing everything in sight and knocking Barnabas aside like a rag doll. Together Barnabas and Julia press the door closed, locking him inside.
Happy families are all alike. Unhappy families are unhappy each in its own way.....
