This episode again is just transitional before the real fighting begins.
Neji uses his eyes to look past the barrier and can't explain what's happening, but Kakashi discovers that this is a Five Seal Barrier and would require all five seals to be removed at once.
Neji pinpoints the seals and the other 4 are in distant locations.
Team Gai split up 4 ways and locate all the remaining seals.
Meanwhile Akatsuki member's are starting to leave and Sasori tells Itachi that the Kyuubi will be his and he and the his colleague stay behind to welcome the outsiders.
All 5 seals are removed and Sakura destroys the boulder, at the same time some enemies are beginning to appear in front of each of Team Gai's members.
Inside the hideout it seems as though the monster/statue thing that was used to contain the monster sucked out of Gaara is transported elsewhere as the head of Akatsuki cast some seals and they both vanish from the "hideout". Team Kakashi know they are already too late when they see the two remaining Akatsuki members sat on the lifeless body of Gaara.
They didn't need to figure out who has the Kyuubi inside of them when Naruto flips and starts calling up his Kyuubi strength in a bid to launch an all out assault on the Akatsuki.
Again not much content in this episode, I am a bit disappointed with the quality as there were some scenes where the quality had dropped a bit. Looks like the fighting will start next week, but seeing as it might be split into 5 fights I expect this might take sometime before any more story progression...
