Ellen goes for Wes - But what's his motive?

More information in episode 9 season 2 of Damages, as the crooked detective orders Wes, Ellen's new love interest, to kill her and make it look like an accident. I suspect that Wes is actually working against the unnamed detective - either for a government agency or more likely out of some need for revenge against Frobisher: he encouraged Ellen to kill Frobisher, early on. On the lawsuit strand, Patti's husband being considered by Secretary of Energy, but we know he has skeletons, including his investment in UNR, his ties to insider trading, his affair, and of course his link to Patti. David Pell, he UNR link to the insider trader, Finn, confronts Finn. Patti learning more about Finn, as she gets closer to figuring out what's going on with UNR stock. But overall, the story line is drifting away from Patti/Close, too bad because she's the stick that stirs this drink. Ellen will have to confront her. And what's with junior partner, Tom? Patti tells him she is under FBI investigation, and his reaction is to be made she hasn't told him before; he doesn't even ask why she's under investigation or what they have to fear. Maybe there's more to him than we thought - in one of the flash forwards, we see that Patti fires him and that he, too, wants revenge (and provides Ellen with a gun). My guess is that Wes never tries to kill Ellen, he comes to her for help, and she does confront Patti (that's pretty obvious). Tom may be total wimp, or he may be an FBI informant as well. There's still something off about the FBI agents and the investigation, with its disappearing file, but not sure what.
