Colby offered to help Annie and Emma with her project for school, pleasing both Annie and Adam. Scott told a story about his own science fair volcano fiasco. The family had a lovely bonding moment, but Adam missed JR and Little A. JR was miserable but he didn't want to go to the hospital. He told Marissa it was just the aggressive new cancer treatments. Little A asked if his daddy was going to die. JR and Marissa assured him he wouldn't lose JR like they lost Babe. Emma's planetary project looked lovely, thanks to the group effort. Then, Scott walked Colby out. He warned her against pushing Annie out of Adam's life. As Annie beamed over feeling like a family, Scott couldn't keep his eyes off her. She urged him to loosen up and playfully mussed his hair, but assured him she has no intention of breaking Adam's trust. Meanwhile, Colby updated JR on her Annie plan, noting that he looks like Hell. He assured her he's not drinking again, just sick. Clueless, she praised the powers of Lucretia's healing soup. JR feared he and Adam couldn't make amends. Later, Emma, Scott and Annie came in from playing in the snow and Emma was cold to Adam! Marissa came home, telling JR that Little A was staying over at Tad's...and then spilling about David's blood disease being hereditary. At the Chandler mansion, a negligee-clad Annie was bent on seducing her hubby. Scott watched them from the other side of the French doors.

Tad interrupted Krystal and Rob the builder talking about her new project and offered his two cents on what kind of place she should open. Krystal insisted she didn't want a place like the Comeback; she was ready for a change. Uncomfortable, Rob the builder made himself scarce and Krystal turned on Tad for sabotaging her relationship. They argued about getting into each other's business. Elsewhere, Damon tried to steal a few kisses with Bailey and Liza dropped by to give him his severance pay from the casino. Liza pointed Damon towards a project involving repainting her apartment. Once alone, Bailey wondered why Liza was being so nice. She claimed she likes Bailey and Stuart and wants to help, revealing she misses them a lot. "I came and ruined everything," Bailey sighed, of causing drama between Liza and Colby. Liza assured her the drama was already there, opening up about Colby and Adam. With Bailey's urging, she visited Colby. Before they could really talk, a panicked cry came from the other room!

Angie told Jake and Amanda they'd run some tests on Trevor's DNA. "What if I don't want to know anymore?" she asked. Trevor was healthy and happy and maybe ignorance was bliss? Jake eased her fears. Later, Jake told Tad and Krystal about David's supposed blood disorder impacting Trevor. "It's hereditary?" gasped Krystal. On cue, Marissa appeared with Little A for a play date with Kathy. Krystal sat her down to tell her about the genetic disorder. Jake and Tad gave them some time alone. Outside, the guys talked about David's schemes. Inside, Marissa worried about leaving Little A motherless again and Amanda walked up with Trevor. They all went to the hospital for testing. Tad urged Marissa to tell JR what's going on, while Angie grimly told Jake and Amanda that 85% of people pass the disease on to their kids. Amanda was devastated. Jake pointed out that it hit David late and Marissa had no signs, so they had time with Trevor. "I'm never going to be ready to let him go," said Amanda. She wondered if this was karma for faking Trevor's death. Jake assured her that if Trevor is sick, he'll devote his life to finding a cure. At Tad's, he comforted Krystal, reminding her that David could be faking. As she went upstairs, he wondered if she'd ever kissed the architect. "Goodnight, Tad," she smiled.
