It looks like Howard aka Chimney (Kenneth Choi) and Madison (Jennifer Love Hewitt) will be getting some unexpected company when 9-1-1 returns for its midseason premiere on Monday, March 16. In this exclusive sneak peek of the episode, the two are preparing some meatballs for Chim's birthday dinner when they get a knock at the door, and it's none other than his little brother Albert (guest actor John Harlan Kim), whom Maddie has apparently never heard of before.
