Total Yandere. I think he killed Petunia in A bit of a Pickle cause she was being friends with Lammy. And she only killed Flaky to stop her from telling the cops she killed Someone and he had no intention killing Handy he was just in the road. This also explains why he killed all of Lammys friends in Royal Flush.
