Seen ch. 22 now, bit more disjointed than 21. Had a montage, some personal scenes and a bigger storyline, all bundled together.
They referenced Asajj´s final fight with Anakin (he meets Padme and she sees his scar). Then the light in their room goes out. (Reference to making Luke and Leia?)
The Separatist Commander with the red uniform (from the Desember-gallery) only appears in one sequence, but he was funny. He´s got this twitching eye and keeps yelling that his base can take on hundreds of Jedi! (It´s got a massive set of turbolaser batteries) When only Anakin and Obi-Wan appear on the horizon, he´s disappointed, but then a fleet arrives overhead and all hell breaks loose.
Several ROTS-references in this one (hundreds of Cruisers like the
Invisible Hand, AT-RTs, ARC-170s, Venator Destroyers, a small Juggernaut-like vehicle, Tri-fighters etc.)
Grievous trains with Dooku, and Sidious appears via hologram to prepare them for their "final operation".
Anakin and Obi-Wan grow into war-buddies, they go on all kinds of missions together, while the Separatists wreck havoc on countless worlds (including Kashyyyk).
Finally, they travel to a remote planet where Grievous is said to be in hiding. It´s the snow-planet from the trailers, and they fight a huuuuuuuuge blue creature. Anakin kills it and several natives in masks appear, angry at what he did. Then it ends at this cliffhanger...
