I really want to know what happen to the mother that killed her son because she had that one diese is there a Sleeping Dogs Lie v2 or no

Sleeping Dogs Lie was about two lesbians, one who hasn't slept in days so she takes a bottle of sleeping pills. Not to kill herself, but to sleep.

You're looking for Episode 2.22 'Forever'. And we never learn what becomes of the Mother. We're given the assumption that the husband forgives her and wants to help her, but also that she thinks that she doesn't deserve to live for what she's done.

I guess it's up to the viewer to imagine for themselves what the right thing is.
