Donnie Wahlberg's character, Detective Danny Reagan, will reunite with his childhood friend and former criminal, Micky Patrick, played by Tom Cavanagh, in the February 3 episode of Blue Bloods. Micky seeks Danny's help in finding his missing fiancée. In a previous season, Danny discovered Mickey's connections to a crime family and convinced him to testify against them to protect his own family. However, the Vasquez family believed Mickey talked and put a hit on him, leading Danny to save him. The upcoming episode will reveal what has happened since then. Additionally, the episode will feature Anthony surprising Erin with a stakeout, Jamie helping a former officer, and Frank encountering a woman who confesses to killing her husband.
