Why were there two Walters in this scene?

there ain't 2 Walters. the other is Plartor Bite, a character forgotten due to mandela effect. he was in charge of distributing the meth in the first season, he was then killed during the gunfight between Hank and Tuco

I’m not crazy! I knew it was 68. One after Six Seven as if I could ever make such a mistake!

Actually that’s Mr Mayhew not Plartor, Plartor doesn’t show up until season 6
