The morning after Chelsea and Nick made love, Chelsea finds herself not quite blown away by their first night together. Stephanie later diagnoses Chelsea's "problem": she's just not that into Nick. Steph suspects Chelsea really wants Jett Carver, but Chelsea hotly denies it. Lucas confides in Billie that he's not sure he can handle it if Sami's baby turns out to be EJ's. A giddy Kate eavesdrops and is even more pleased when Billie reveals that Nick stole Chelsea's hairbrush from the lab. Kate dashes over to the hospital, where she asks Nick to make sure Sami's test proves EJ is the father. Nick is appalled. While waiting at the hospital for an amnio, Sami confides in Marlena she's worried that if her baby turns out to be EJ's, she'll lose Lucas forever. Lucas, Sami and Marlena are stunned when Sami's sonogram reveals the presence of two babies. She's having twins!
