In the penultimate episode of the Debt Collector serial, titled RUTHLESS, Lirium/Joe and Elena attempt to track the illegal collections from terminal children. With Lirium's brute force and Elena's tech genius they are able to crack into Candy's accounts and pinpoint the pattern of collection. Unfortunately, there's a new collection scheduled for the next day and Lirium must send out the alert before another life is terminated early. 
 At the end of the last episode, Lirium/Joe saved his mother from collection. And, that's great, at least until she decides her remaining days would be best spent in the pursuit of an experimental cure. 
 Joe is distraught, and wants to prevent Dr. Brodsky from testing his tissue-boosting technology on her, but he realizes it's not his choice to make. Knowing he can't postpone alerting the authorities to Candy's illegal tranfer activity, Joe asks his mother to wait until he returns before beginning the experiment. While his contact wants to help cease the transfers, nothing can be done without hard evidence of the transfers--and the only way to get that is for Joe to confront the rogue collector, Moloch, to save another young life. 
 The action is still high, and the romantic spark building between Joe and Elena seems ready to burn into flame...so huge hopes for the final episode in this excellent series.
