The kiss between Delko and Calleigh occurs on the "CSI: Miami" next week's episode. In "Sink or Swim", the future of Delko in CSI is threatened just as his relationship with Calleigh moves to the next level. He is taken away to prison by the INS for failing to address the issue of his forged birth certificate and when he reaches out to his father for help, he gets none.
Pirates takes over a luxury yacht owned by defense attorney Derek Powell (guest star P. Diddy) who was suspected of protecting a criminal in a previous episode. Horatio and the team investigate the murder of Powell's fiancee Nadine Walcott but the case is sidetracked when Delko who has the evidence against prime suspect Ken Taber, is thrown to jail.
"Sink or Swim" airs March 2. Also, Sofia Milos returns as Yelina Salas, a detective with the Miami-Dade Police Homicide Division who often assist the CSIs in cases.
