I like the idea of Renee becoming so extreme she scares Jack Bauer. It's kind of like when Doggett joined the X-Files, and Scully had to become the believer :) And "You can be a guy with one thumb or a rich guy with one thumb" is a pretty good argument.
The Katee Sackoff plotline is this year's "Kim in the beartrap". Apparently you can join a super-elite counterterrorism agency using a fake idenity while having a criminal record. CTU continues to be even more dysfunctional than actual Homeland Security.
