So some interesting spoilers for Sunday's finale:
What can we expect between Calleigh and Delko in the CSI: Miami finale? — Jennie
ADAM: Executive producer Barry O'Brien says the 10th season-ender is all about family — specifically for Calleigh, who will take the necessary steps to finalize her plans to adopt two young children. But Delko will very much play a part in Calleigh's new family. "It's about saying, 'You're not going to be alone,'" O'Brien says of Delko's actions. "He will make a declaration that holds a lot of weight with both the adoption agency and with Calleigh. ... I think we're taking that relationship to the inevitable place we've always imagined."
