'Baby Daddy' Season 4 Episode 18 Spoilers: ABC Family Flash Forward Gives Glimpse of the Future

Tune into ABC Family tonight to catch the "Baby Daddy" flash forward special.

Fans get to see a fun romantic flash mob as Brad (Peter Porte) proposes to Bonnie (Melissa Peterman) in Episode 18, titled "Parental Guidance Suggested." Will they really get married in the future?

"We first came up with the idea that we wanted Brad to propose to Bonnie, and it just sort of grew out of what that story needed," executive producer and creator Dan Berendsen tells TV Insider. "I went to my line producer and asked how he'd feel if we shut down New York Street [on the CBS Studio lot], hired 50 dancers and threw a flash mob...and he was like, let's do it!"

Porte made planning the flash mob easy since he has a background in singing and dancing.

"When you hear him sing, as a writer, you go 'Oh he can't just carry a tune, he can carry a number!'" Berendsen says of the actor who landed his first gig with "Mama Mia."

In the last episode, "Wheeler War," Riley (Chelsea Kane) and the boys joined a game to fight over her boyfriend.

"Ben (Jean-Luc Bilodeau) realizes that he made a huge mistake when he drove Riley away; he never should have believed Danny and Riley have feelings for each other, especially since they're now dating other people," according to the official description. "Ben knows Ross (Eddie Cibrian) is all wrong for Riley, so he devises a plan to get rid of him; he's going to turn Ross into a Wheeler."

Although Riley and Ben were playing for Ross, they didn't want him to know, so they said they were fighting for Bonnie's right to play poker, according to the episode's recap on SpoilerTV.

Meanwhile, the love triangle between Ben and Riley is still going on. He just can't seem to get over her.
