This is all very fascinating to read!!! I was also thinking that when it was just Lily and Stumpy, there didn't seem to be an Alpha - Stumpy and Lily were just best friends, and that was it. It wasn't until we brought Smudge into the mix and she also became Lily's best friend that Stumpy began to assert her dominance - nothing aggressive, but she definitely made sure Smudge know she was the first cat.
