You wont expect the twists and the tragic shocks of this penultimate installment. The reasons of Cheng's attack and whereabouts, the fight of Chloe to free herself from the Chinese, the sacrifice of Heller and Mark (the moment in which is confronted with Jack and Heller about his dark side with the Russians is the culmination to the whole story arc since the first episode) for a greater good, the Audrey's help...
Then you have the suffering from Jack and Kate. Two tortured souls in the middle of a global crisis. But the most important thing is not exactly that crisis, but their personal powder to go ahead and end everything with a glorious bang. These characters are the best of the miniseries and their plots carry the quality of the show to the highest possible after all that we saw from the 24 universe.
The performances are unbelievable, the script is taken to extreme levels and even having all that plots together in the final episodes, everything is approaching to a explosive and dramatic conclusion. Although I think that the best word is not dramatic but tragic. Really tragic. If my thoughts are right, get ready to watch next week the most exciting, epic and saddest finale since the first series of the original run.
Now everything is done. I'm thinking of this season like the last of all. Everything has been set. Now it's time to conclude.
