24

When Quinn starts to cut Burnett's throat, you can already see the red line of fake blood on the left side of the throat.

The clock at 08:11:52 is silent, marking the death of an important 24 character. This is the ninth silent clock of 24, and the second time this season (the first being when Renee Walker is interred by Jack and Tony in "12:00 P.M. - 1:00 P.M.", not counting the sound of her breathing). This is also the second instance of a silent clock in the middle of an episode rather than the end (the first being when George Mason leaves CTU in "Day 2: 9:00 P.M. - 10:00 P.M.").
