Curtis Stalano was a peer of Trent Lane and Jesse Moreno (and thus Tommy Sherman) at Lawndale High.
He appeared in "Road Worrier", working in a toll booth. Trent and Jesse were left stunned and traumatised by the encounter: "He graduated with us. Now he's working in a toll booth. Whoa." In an act of defiance, Jesse declared you'd never find him working
at all in a job like that.
Curtis presumably recognised Trent as well, but whatever reaction he had is unknown.
