Lazlo was one of Dunkelvolk's Nazi henchmen.
In 1947. he and another henchman, armed with rifles, were at the Bahnhof Berlin Zoologischer Garten overseeing the train's preparations and guarding crates with armaments. As the other explained to him, although the train was regularly scheduled, they were waiting for sealed cars to be attached at the rear of the train for them.
After passing some checkpoints, Dunkelvolk ordered the two to check with the guards. While his colleague inspected the fourth compartment, he found Major Nadia Kirov looking for the pieces of the Philosopher's Stone they had acquired for Matthias Jäger. Kirov hit and beat the henchman, but was eventually restrained by Dunkelvolk.
At dawn they reached Koblenz. Lazlo and the beaten henchman led Kirov to Klaus's truck; their job complete, three henchmen retreated to the station for a morning coffee.
