From Yoda at AMC Board:

Tad, Dixie, Ryan and Annie all toss out accusations at the others that they've taken Emma and are hiding her somewhere. Meanwhile, it's David who has the tot locked away at his cabin. Kendall is unnerved by Del's suggestion that he and Zach work together on a book about Greg's murder. Although he's spitting nails over the situation, Adam cools down and assures Babe he won't say a word about her cheating to JR. Babe is hit with a wave of guilt over her big secret, but Krystal tells her daughter she's doing the right thing by not telling JR about her affair. At the same time, however, Josh tells Bianca that he's itching to reveal the truth to JR. JR overhears Josh pushing Babe to dump her hubby, but she insists she wants her future to be with JR. When JR makes himself known, Josh announces that he and Babe slept together. Meanwhile, Colby sets out to make Sydney pay for her part in Sean's decision to reject her. Kendall's fight with Babe delight's Zach, who is glad that the feisty woman he fell in love with is back. Annie turns to Tad and Dixie when her decision regarding Emma leaves her in agony. Jonathan gets a gentle word of warning about butting into Amanda's personal life.
