JoJo is mad, panicked, and looks like she brought a machete. So Ben tells her he loves her some more! And that his feelings haven't changed. But, no Neil Lane ring for her. Then he tries to get out of it all by saying JoJo wanted him to be honest, and that's what he's being. Not this kind of honest, dude. Now is the time when even the best men in the world should lie their damn faces off. Or at least omit the whole love part.
JoJo lets me down here. She could've done so many things, so many harsh, brutal, reactive, strong things, like telling him and his love to fuck off, or stomping on his toes with her heel, or rubbing a bunch of dirt on his suit so Lauren B would never, ever respect him again. But instead she lets Ben give her a big hug and walk her to the limo, and she hops in, to cry and smoke the provided Jamaican spliff that probably isn't even made with very good weed.
Ben whips out his phone, and instead of sending JoJo a bunch of Cupid emojis, calls up Lauren's dad, and does the most casual, presumptive hand-asking in history. He says yes, and Lauren B gets off the chopper and comes over. Ben's all smiles this time. She gives a far more boring and boilerplate Love Speech than JoJo did, and tells Ben that he's her "generally lifeless, pale representation of a human being", or something.
