Voices is the 8th episode of NCIS Season 15 and also the 338th episode of the entire NCIS series.
An NCIS person of interest in a bribery and fraud case is found murdered after a runner is led to his body by a strange voice while McGee and Delilah disagree on whether to find out the baby's sex or keep it a surprise.
- Because of the circumstances behind Delilah's paralysis, she and McGee had a blood test to find out the gender of their baby, as an ultrasound would have caused complications to her injury.
- Delilah's blood work reveals that she's pregnant with twins, one boy and one girl.
- At the 40th minute of the episode, after Amber said to Gibbs that he "seemed disappointed" that she didn't hear voices, Michael Franks appears, and says to Gibbs : "Well, Probie, was she wrong ? 'Cause hearing voices, seeing dead people. I don't know... Psychic seems like a better option than the alternative.". Then, Gibbs leaves his office with a smile.
