The climax of Day 5 is going to be finding that Kim is the brains behind Logan.
If Logan had Palmer killed then was he also the one trying to kill off everyone who knew Jack was still alive? If so, how did he find out? Not from Palmer, Tony, Michelle, or Jack. That only leaves one person -- Chloe.
it seems the two of 'em put together may have half a brain
You're probably closer to the truth than you think.
The plots that turn out to be diversions for other plots...which are diversions for other plots...for other plots...etc...will probably wind up with Kim as the final plot in charge of a gigantic lesbo brigade to take over the world.
Jack winds up killing off his own daughter...but he's sorry.
Don't get me wrong though, I'm a 24 addict but you have to suspend reality. But that's ok too cuz I need a break from reality.
