Letty (Michelle Dockery) has just crossed a line.

And then now she has killed not one but two people within the span of 10 seconds.

Coming out of that, it was always the design to have her kill Teo.

The last two scripts were really good, but they were feeling to me a little bit straightforward.

If Letty had just killed Teo, hes like the bad guy.

We want him dead.

Its good but its sort of just not that surprising.

And it should be just some random innocent person because Letty wouldnt feel that bad about just killing Teo.

But she feels really bad about killing this innocent person.

And it sounds like fans can expect this ordeal to affect how Letty relates to Javier.

And now, of course, its like, well, we have to have her kill someone.

Good Behaviors season 2 finale airs Sunday at 10 p.m.
