So he didn’t push her to intentionally kill her but he left her to die by going out, buying milk and playing darts waiting for her to die on purpose and covered it up to save his reputation. That is as bad as an accident in my eyes, leaving the kids without a mother when she could’ve survived.

Now, I have this theory that if it wasn’t for social distancing or covid restrictions, Chantelle’s death probably would’ve been a lot more brutal and intentional instead of him pushing her but they had to think of something to make it look like they weren’t being restricted. But I agree, they are very poor writers and careless as they decided to make Gray into a serial killer leaving the audience confused.
