During Day 5, agents at CTU discovered that Collette Stenger, an important collaborator of Vladimir Bierko (their main target) was being covertly followed by German intelligence agent Theo Stoller. Jack Bauer, without permission from his superiors, promised Stoller the entire WET List in exchange for his help in apprehending Stenger. Bauer then had Chloe O'Brian steal the list from the NSA's mainframe and send it to his PDA. Theo reviewed the list for a moment to his satisfaction that it was real.
