'Happy Endings' Producer Foretells Season Three's Changing Love Lives

(WARNING! What follows may spoil some aspects of the upcoming third season of ABC's "Happy Endings." If you don't want to know, now's the time to turn back.)

When ABC's "Happy Endings" begins its third season this fall, romance will come, go and shift. The Insider caught up with the cast recently, and it seems Dave and Alex will be making some of the biggest waves starting the series' latest chapter as a couple with an uncertain future ahead.

"A lot of times, we try to do what feels like the most real thing but we never did the whole breakup/makeup thing with them because we tried to find out who those characters were individually," said executive producer Jonathan Groff. "So many couples reexamine their feelings for one another after an explosive breakup, so Dave and Alex will explore if there's still love between them.

So, where will that leave Penny? She'll ultimately have a new man in her life, Groff admitted. Big hint: it won't be wheelchair-bound Brian Austin Green. "For all her foibles, Penny's a good friend so she could go down that road with Dave if there was a clear path. She had to step away from it when she saw Alex might still have feelings for him," Groff said. "Plus, I'm just excited to explore Penny in a real relationship . . . and see how she wrecks that."

Since, as Adam Pally put it, "There's something fun about seeing Max being a romantic bumbling idiot," he could also have more love in his life. Writers are also reportedly all giddy-like about Grant being out-of-work and exploring a life more "Max-like." It sounds like the interplay between the two will be a basis for a reported season-long theme of flashbacks to their friendship's beginnings.

Groff also claimed that writers want Stephen Guarino, Megan Mullally and Michael McKean back to reprise their respective Season Two roles as Derrick, Dana Hartz and Big Dave Rose. Producers are also seeking players to debut as Alex and Jane's parents, with a dream "get" for Groff being a "24" reunion of Kiefer Sutherland playing Elisha Cuthbert's father.

"He'd be so amazing to get, and such a great presence. Plus, with how we're conceiving the character, he would be perfect for it. We're not making an offer or anything, but it would be great for him to do it!" Groff said.
