Rebecca says something fishy is going on between David and Ivy, perhaps Ivy is using David to break up Sam and Grace. Rebecca says it is odd how David suddenly showed up in Harmony claiming to be Grace's long lost husband. Rebecca then wonders aloud if Ivy hired David to break up Sam and Grace. TC thinks Rebecca's theory is interesting, but he says Sam checked into David's past and the marriage. Rebecca says Ivy does have the money to manipulate those things, but if David isn't Grace's husband, then John isn't her son, and no amount of money or power can change DNA. Rebecca says she is being silly, and letting her imagination run wild, but the thought has been planted in TC's head. Rebecca leaves, and Eve returns as does Sam. Eve asks where Grace is? Sam says Grace is upstairs apologizing to Ivy for causing her pain! TC then suggests to Sam and Eve what Rebecca suggested earlier, what if David isn't Grace's husband?

Meanwhile, Simone and Jessica spy on Kay and Zombie Charity, and think Kay is up to something. Kay comes up with a new plan, and whispers orders to Charity. The Zombie asks her if she is sure, this is really going to hurt? Kay says she will. Kay asks Chad to play a slow song later tonight, and when he sees her and Miguel, and Charity and whoever she is with near one another, he should announce a partner switch so that Charity and Miguel can dance. Miguel puts on a slow dance song, and Kay tells Miguel her plan so he can dance with Charity. He is touched that she would do that for him, and gives him a kiss on the cheek.

Still, Sam doesn't think David is a threat to his marriage, but then recalls finding David in Grace's arms earlier. Still, Sam says everything says David is legit, and he hasn't fought them. TC still thinks this whole thing is a lie manufactured by Ivy Crane to break up his marriage. TC is positive something is going on between David and Ivy. As TC rants and raves, David shows up and overhears his theories. TC suggests they have a DNA test run to find out if John is Grace's son. David hears this and realizes that they are onto Ivy. Sam tells TC that he can't ask Grace to do this. As TC pushes him to do it, Grace shows up and asks them what all this non-sense is about John not being her son. Sam tells her to calm down, and says that TC thinks it is possible that Ivy hired David to break them up, and that John isn't her son. Grace doesn't believe it, and Sam says neither does he, but they don't have rock solid proof that John is her son. He suggests they have a DNA test done, just to be sure. Grace refuses, and tells TC that his anger at the Cranes is making him come up with this scheme.
David goes back to see Ivy, who is in pain, and tells Ivy that they are onto him. David tells her about TC's theory, and how he is explaining it to Sam right now!

David hopes there is a way out of this, but David hopes she is caught. David leaves, and Ivy says she will not fail!
David goes back downstairs to face everyone, and TC asks David if Ivy hired him to play Grace's husband? Grace says David should be treated like this! TC says he wouldn't tell them the truth anyways. Grace says she knows she is John's mother, but if the rest of them need hard evidence then they will do the DNA test. TC asks David if he objects to that? David says no, but TC thinks he is bluffing. Eve says she'll make the arrangements.
