Jack Bauer takes the night off (episode 18)

Jack Bauer decided not to accrue any statistics tonight, and when Jack Bauer decides not to accrue statistics, you let him.

One "DAMMIT!" from Chloe. Guess that's it.

This brings our season totals up to:
Total Jack Bauer-caused fatalities: 22
Total utterances of "DAMMIT!": 22
Total Jack Bauer-uttered "DAMMIT!"s: 11

Which leaves us with these season averages:
JBKpH (Jack Bauer Kills per Hour): 1.222
DpH ("DAMMIT!"s per Hour): 1.222
JBDpH (Jack Bauer "DAMMIT!"s per Hour): 0.611

Yep.
