This was inspired after seeing the Cover Art for Episode 26.

Mr. Whiskers was Scratch's cat! Scratch was living at the apartment complex before it all happened.

That's why Angel was familiar to her. She saw him when he visited his girlfriend Cindy.

And the real reason why she has it in for Pegs: She took her cat!

And that special thing she was looking for after the Tower collapses: Mr. Whiskers.

It would also explain where Scratch got her trademark looks. Mr. Whiskers is as feisty as his original owner.
