Why would Flynn want to get involved in the case?

  • Everyone knows it’s dangerous. Flynn was there when Brennan got framed and when a dead body showed up in Hodgins’ bedroom. Everyone involved trying to bring him down is risking his life.
  • (In the fake world) they may never catch Pelant. It looks like a dead end. So if he’s looking for a golden star on his FBI record, that’s not it. 
  • Flynn and Booth are definitely not friends. They may have respect for each other but they’re not close enough for Flynn to “use favors” as important as those for Booth’s pretty face.

[edit note] When he and Booth got to Pelant, he was the one to shout “Pelant”. Way to warn him of their presence Flynn…
