Good Behavior
Letty (Michelle Dockery) spirals out of control after committing murder on “Good Behavior.” TNT

Just when Letty was ready to get back on a semi straight and narrow path, her world was turned upside when an intense moment resulted in her committing her first murder.

On the “Good Behavior” Season 2 finale, Letty will be forced to face the decisions she has made and from the looks of the episode 10 sneak peek, she will not be able to run from her problems like she has done in the past.

In the clip for “Letty Raines, In The Mansion, With The Gun,” Letty (Michelle Dockery) is constantly confronted with murder. In the sneak-peek video from the TNT series, the troubled mother is seen playing a game of Clue with Jacob (Nyles Julian Steele), Estelle (Lusia Strus) and Rob (Joey Kern).

As Letty scribbles away trying to solve the murder mystery, Jacob informs her that she is the killer. Letty then questions Jacob, doubting that she is the murderer. Estelle and Rob go on to state that Letty’s character, Miss Scarlet, committed the murder with a rope in the conservatory.

Jacob then asks Letty whether the mansion Javier (Juan Diego Botto) brought her has a conservatory and she tells him it doesn’t. Estelle then makes a comment noting that not having the room is probably for the best because Letty would just kill the plants.

Estelle then lifts a cactus off of the floor which shocks Letty and causes her to examine the plant. In the previous episode of “Good Behavior,” Teo (Juan Riedinger) held Letty at gunpoint as they waited for Javier to arrive back at the mansion.

When Teo was briefly distracted, Letty used a cactus to hit him on the head which gave her enough time to run to her bag, grab a gun and kill him.

Shocked by the fact that she just committed murder, Letty held on tight to the gun but realized the employee who was hired to install the home security system had arrived. As Letty shouted at the man not to leave, her gun went off once again, committing her second murder.

Since “Good Behavior” premiered on TNT, Letty has consistently criticized Javier for making a living as a contract killer. However, now that she is the killer, Letty may not be able to handle the constant reminders of her crimes.

The “Good Behavior” Season 2 finale airs Sunday at 10 p.m. EST.
