Great news for fans of the Ryan/Esposito bromance! At Comic-Con, Jon Huertas (Esposito) revealed that the wisecracking colleagues will light up our small screens with substantially more scenes in Season 4. Score!

But it's not just fun and games. Jon told Wetpaint Entertainment that Ryan and Jenny's upcoming nuptials might cause some friction. "Ryan is entertaining the fact that Castle might be a good best man because he has money to throw him a dope bachelor party," Jon dished. "So I need to figure out, what can Esposito do to become the best man? Aside from choking Castle out and leaving him in a closet somewhere."

That's not it, though. An upcoming episode features a double date with Lanie/Esposito and Ryan/Jenny. Sounds exciting, but there is one teensy problem: "Maybe the two girls don't get along," Jon teased. Hmmm. Ya don't say?
