S4·E24 Crossroads

After attorney Jennifer Nichols disappears, the team investigates the last few days in her life and soon find that she had grown disillusioned with her most recent relationship with Allen Davis. Discussions with a married ex-lover reveal that Nichols had recently gone through an old case file relating to a ten-year-old bank robbery, which has a connection to her recent relationship. Jack and Ann avoid discussing a recent development in their relationship -- her pregnancy.
