Nora is worried about Lindsay who seems to have been stalking them since returning from Miami. Jen recalls her mom's revelation upon returning from her trip, which was to Africa and not Miami. Nora is asking if Lindsay actually still loves Troy and interrupts Jen's thoughts. She quickly denies that her mother loves Troy and doesn't want to be in the middle of this whole thing. Nora apologizes but immediately places her squarely in the middle by relating Lindsay's latest doings, from giving Troy the painting to wearing a copy of the amulet. Jen is perplexed but Nora believes Lindsay to be obsessed with Troy. Jen makes excuses for her mother's behavior (as well as her own).

Upon taking the C.V.S. test, it's become apparent that there is a variant in Chromosome 8, she tells them. It could be inherited which might be that it would be of no consequence or it could mean that the child could be developmentally challenged. More tests will have to be run to determine if it's caused by heredity. The doctor requests Liz's medical records, which should have been sent, however they are not on file. The doctor wants blood samples from Liz and the baby's father. Keri wants her family nearby so Antonio calls Liz.

She will visit her if Addie really needs her though and no, she's not in trouble, she tells her mom. Hank runs into Todd in his nun's habit and finds it rather fishy that he's right outside Addie's door. He doesn't believe Todd's response, "I'm doing God's work."

She may marry Cris after all since Natalie has turned around and married someone else. She assures Lindsay that she didn't tell Nora any of her secrets, but her torture of Troy seems to be working.
