Pizza slicer

I had a professional quality pizza slice, years ago. Threw it out in a pizza box. I miss that thing...

I think the missing pizza slicer and I think it was a mug that he mentioned was missing were everyday items he misplaced in that very messy kitchen they showed the viewers. Mare was smirking a little as she wrote down those two items on her pad but then changed the moment he mentioned a gun. He was obviously a grieving widower just kinda finding his way…he stated something along those lines to Mare at the onset of their conversation.
