Detective Jody Powell is Peter's daytime partner. The two were purposely paired together by Capt. Blaisdell because Peter had worked with Jody's sister prior to her death. Peter blamed her(Kira's) death on himself, but Jody knew that to be untrue.
Jody also likes Peter in a romantic way, but he is unaware.

"What if I did look behind me. What would I see?" - Peter to Jody
"Someone who cares about you, who worries about you, and someone who could
truly love you." - Jody in reply
