A decidedly un-merry Christmas seems to be in the cards for those in the TAC office as Bull and Benny (Michael Weatherly, Freddy Rodriguez) represent Marissa (Geneva Carr) and Greg (guest star David Furr) in federal court, where they face charges of money laundering and fraud associated with Greg's restaurant. Among the biggest challenges for the defense: convincing a jury that Marissa was clueless about Greg's business dealings. Yara Martinez and Christopher Jackson also star in the new episode "The Ex Factor."
