The writers feel that it is time for Adam Rodriguez's character to be back on the crime scene after missing from several episodes in two seasons.
After missing from several episodes, Eric Delko will be seen regularly on the "CSI: Miami" team again. Announcing through Twitter was the character's portrayer Adam Rodriguez who wrote, "Twit Fam, I have some news that I hope will make CSI:Miami fans happy. Eric Delko will be back to the show full time 4 all of season 9!!!"
CBS has also confirmed the return although did not go into details when he would be seen regularly since. Following a series of traumatic events in Eric's life, the character was written off in several episodes in late season seven and the current season eight. While his character is in and out of the unit, Rodriguez spent his time filming a recurring role on "Ugly Betty". But now that ABC has announced that "Ugly" is coming to an end, Rodriguez will have the time to concentrate on "CSI".
Meanwhile, TV Guide said that "Delko will return when Calleigh faces a life-and-death situation at a crime scene. While he's around, he'll also launch an undercover investigation of the CSI lab for the State's Attorney's office."
Co-executive producer Barry O'Brien supported this, saying "They're going to face a defining moment of decision. All the starts and stops in their relationship are going to be put to the test and they will finally make a decision that will inform their relationship for the remainder of the series."
