Prologue: Previously on CSI...
This story will make very little sense if you haven't read 'Who Would Try', it's predecessor. It's been a while since I finished the first story so here is a summary of it, just in case anything is missing...
Basically, after Ecklie splits the graveyard shift up in the episode 'Mea Culpa', Greg decides to fight back, and try to somehow reverse this detrimental scenario. Before he can act, however, the events of 'Nesting Dolls' take place (i.e. Sara yells at Catherine and promptly gets suspended by Ecklie for yelling at him too). In fact, Ecklie goes one step further and tries to fire Sara.
Greg learns (with a little help from Archie) that this is because Ecklie caught Sara on a hidden camera looking through what Ecklie thought was his confidential record. It was, in fact, her own record. As Ecklie's record contained information that Sheriff Atwater would find very interesting, it was in Ecklie's best interests to ensure Sara's dismissal. But, by using Catherine in an elaborate double bluff, Greg sets Ecklie's plans at nines and Sara remains with the crime lab.
Shortly afterwards, the millionaire casino owner Bruce Eiger jumps off his own balcony, leaving behind a legacy of intrigue, hidden secrets, and soiled diapers (see 'King Baby'). Ecklie recruits Greg, who we now learn has been in his confidence for some time now, to retrieve Eiger's hidden files on all of Las Vegas' most prominent citizens. After a brief escapade with Nick and Sara, he succeeds, and brings Ecklie the files.
It is at this point that Warrick works out at least part of what Greg is up to. By comparing notes with a guilt-ridden Catherine, an angry Nick, and a confused Sara, he finds out that Greg stole evidence from the layout room, and learns of Catherine's role in the double bluff. He is rudely interrupted from his thoughts by a gunshot echoing through the lab...
Greg arrives at Ecklie's office and promises him enough dirt on Grissom to get him arrested in exchange for Ecklie leaving Sara alone. Blinded by greed, Ecklie readily agrees, and promptly learns that Greg has set him up, and has been working with Sheriff Atwater all along. After a desperate, ultimately futile, bid to escape (during which a gunshot echoes through the crime lab), Ecklie is arrested. The lab is rocked with celebrations. Greg is confident that Ecklie will give up the name of his contact outside the crime lab, and suggests that Grissom fill the vacancy of assistant director. The sheriff, however, has other ideas...
Anything I've missed? Oh, yeah. Greg and Sara are drifting steadily closer, and Grissom is dating Sophia Curtis. No one knows...well, Nick might have an inkling...
