Call it the curse of being on the bubble: After 10 roller-coaster years, CSI: Miami will end its season without a major cliff-hanger.Barry O'Brien tells TVGuide.com. "It is a far more personal ending. You're left with this feeling that the team is a family."But the foundation of that family will buckle a little. Sunday's finale (10/9c, CBS) opens with Ryan Wolfe (Jonathan Togo) bloodied and unconscious in a strange place. When he comes to, he sees the dead body of Assistant State's Attorney Joshua Avery (Ryan McPartlin) and instantly becomes Suspect No. 1. "We find quickly that Ryan is exonerated... but as we dig deeper into the evidence and what transpired, another one of our own falls under suspicion," O'Brien teases. "Horatio & Co. follow this evidence, regardless of where it leads — even if it's a painful place. There's a chance one of our own has crossed the uncrossable line."(Possible spoiler alert: Cast member Eva La Rue has signed on for ABC's Mandy Moore comedy pilot. You do the math.)Yet O'Brien insists that Horatio (David Caruso) and his team will persevere. "There is a certain amount of betrayal and heartbreak in the finale," he says. "But there is also a sense that going through this is a galvanizing force. The team that remains is stronger than ever before. In telling this story, the bond between our characters is very much reaffirmed."Emily Procter) will finalize her plans to adopt. But thanks to Delko (Adam Rodriguez), Calleigh may not be a single mother. "Calleigh is a single woman who has a challenging, demanding and often dangerous job," O'Brien says. "Light is shed on all of that in the adoption process, and it's not until a very impactful show of support comes from Eric Delko that she is granted custody of these two young children. There's been sort of an up-and-down trajectory for them for a number of seasons now, but you get a sense of a really strong future for these two characters."Does that mean if the show earns a Season 11 that Calleigh and Delko will be a couple? "This is a personal expression of support and admiration and a promise of a presence in Calleigh's life and the lives of these children," O'Brien says. "It does set the table for a deepening personal connection. I feel like we finally earned the right to progress their relationship fundamentally in this way."While O'Brien waits to hear about the show's fate, he is actively planning a Season 11 that continues the thematic exploration that began this season when Horatio was repeatedly bested by the powerful Navarro family.
