Judy is on a cruise ship and wants to go into the sauna.

No one is there, so she opens the door and a dead body comes out.

McGee is shocked to learn Judy was on a cruise and ddn't tell anyone.

That did not sit well with anyone else, especially Delilah who is struggling with the fact that her mother has this secret life.

It all comes to a head when her home is bombed and she lives with them.

She says she wants to have her book club and everyone tells her she doesn't understand the severity of her actions.

A delivery comes and it looks like the man is trying to get a gun out. Parker and McGee tackle him.

We then learn the man is Judy's ex-fiance and she didn't tell anyone.

Judy figures out the case is due to toxic waste and the particular brand of drink on the CCTV was not on the ship.

After some digging, everyone realized that it was the company putting toxic waste on the boat to be thrown into the water and Finch was to blame.

Parker introduces an app to the team to help them come together, but it has the opposite effect.
