On the surface, Lolly and Jocasta did not show a striking family resemblance. Jocasta was tall, where Lolly was short, with wavy blonde hair and bright blue eyes. And Jocasta was slender, somewhat sharp and austere, where Lolly was attractively rounded in all the right places. Looking closer, though, I could see the resemblance. The same cheekbones. The same mouth-a little small for the face, with good teeth. And, of course, both had datajacks high on their right temples.
