Jonas and Mark attempted to loot the abandoned car park in Houndfield. After turning on an emergency generator to start some UV lights, they were swarmed by infected. They managed to escape, though Jonas was injured when part of a wall collapsed on him. Upon meeting Aiden Caldwell at the entrance to the car park, Mark gives him some lockpicks.
After Aiden successfully returns with supplies, Jonas, Mark, and Klaus meet him outside and thank him for making their job easier. Regardless of whether Aiden offers to split the loot or threatens them, Jonas and Mark as well as two unnamed heavy thugs attack him. Aiden can either fight and kill them, or run away. Upon returning to Hubert Kerbatsos, Aiden learns that Hubert originally tried to double-cross Dodger, and hired Jonas and the others to make it seem like he was robbed. However, they decided to instead turn on Hubert and bring the supplies to Dodger themselves.
Mark:"How're you holding up?" Jonas:"I'll be fine. H-How 'bout you?" Mark:"Who are you?" Aiden:"You guys need help?" Mark:"We'll be fine. Thanks." Aiden:"What happened?" Mark:"We heard... a rumor about this garage." Jonas:"We thought it'd be an easy score. But... we were wrong. Dumbasses." Mark:"Hey! Hey, at least we got far enough down to start up the old military generator and juice up some UV lights." Aiden:"So, what happened then?" Jonas:"Further down, the underground parking is fuckin' swarming with Infected." Mark:"Barely made it out of there alive. And then part of a wall collapsed on Jonas on our way to the surface." Aiden:"You won't mind if I give it a try, do you?" Jonas:"Knock yourself out. But it's probably not worth it, unless you wanna end up like me. Or worse." Aiden:"I gotta make good on a promise." Mark:"Here. If you manage not to die, maybe you'll find use for these. We sure ain't going back. Not that way, at least." Aiden:"Thanks."
(Upon returning with the supplies) Jonas:"Wow. You made it." Mark:"Did you find the stash?" Aiden:"Sure did. Thanks for the lockpicks. But... what're you still doing here?" Klaus:"Is this him?" Jonas:"Sure is. Was kind enough to get the goods for us. Saved us a lotta trouble." Klaus:"Very gut. So, vere did you find out about zis?" Aiden:"A little bird. What's it to you?" Klaus:"Vas it a little bird mit a broken leg?" Aiden:"How would you know?" Klaus:"Because I broke it." Aiden:"Why'd you attack him?" Mark:"Hubert was trying to take the goods for himself. Tell Dodger he didn't need anything. Needed our help to pull it off." Klaus:"But we didn't know why we needed Half-Assed Hubie. And now we don't need you. So, give them to us." Aiden:"Three against one? I like those odds." Klaus:"Count again."
