As he is last in order of "freshness" Erf-b1-p027, it is possible that Ensign Toast was one of Stanley's earliest warlords. It is possible that Stanley replaced him with Sir Leeroy Jenkins. Alternatively, Stanley could have selected another warlord whose body was too ravaged in battle to be uncroaked by Wanda, and choosen Sir Leeroy Jenkins later.
