While General Oro Dassyne muses as to how many Jedi it would take to overrun his base on Bomis Koori IV , a scout battle droid reports that Jedi are approaching — and the general is surprised to discover they number only two : Obi - Wan Kenobi and Anakin Skywalker . Under a barrage of firepower from overhead Republic Attack Cruisers and ARC - 170 starfighters , the two Jedi take the base in seconds . A montage shows several of Skywalker ' s heroic exploits during the Clone Wars : destroying several droid tri - fighters in a daring dog fight alongside Saesee Tiin , and rescuing three Jedi ( Voolvif Monn , Aayla Secura and Agen Kolar ) from attacking crab droids . Skywalker ' s starfighter lands on Naboo , and he and Padmé Amidala have a moment as she sees his face scar for the first time . They proceed to spend the night together . Obi - Wan Kenobi wakes in an uncomfortable trench , as Commander Cody reports that their barrage on the nearby droid base might succeed in lowering the shields in about three months . Kenobi points out that they have been there a month already , to which Cody replies that they are right on schedule . Skywalker enters bearing " lunch " , a cloth full of live insects and worms , which he casually reports he got from " inside " the CIS base . The two Jedi make their way through the sewers under the base . Skywalker wants to fight the droids , but Kenobi simply blows up the shield generator by using small spherical bombs and pointing out that there are alternatives to fighting . With the shield down , their forces invade the CIS base . On Kashyyyk , two Wookiees , Tarkov and his son Jaccoba are hunting when they come across a camouflaged CIS droid invasion army . Across the galaxy , the droid armies continue their relentless invasion . In an unknown location , Count Dooku spars with General Grievous , urging him to use more unorthodox bladework . As Dooku disarms Grievous and advises him that he can only maintain his edge if he has fear , surprise and intimidation on his side , a hologram of Darth Sidious appears , commenting on Dooku ' s wise counsel . When Grievous reports that the Jedi numbers are thinly stretched across the Outer Rim in an effort to contain their attacks , Sidious congratulates them , and orders Grievous to begin his " special mission " . On the conquered battlefront , Kenobi and Skywalker receive an urgent message from Supreme Chancellor Palpatine and Mace Windu on Coruscant . Informed that liberated systems were retaken by the Separatists , and that Palpatine ' s spies have located General Grievous on the planet Nelvaan . Kenobi ' s battle fleet arrives in the system , where they detect no enemy forces on the planet surface , but find the planet in the grip of a sudden ice age , accompanied by some strange geothermal readings . Landing on the planet surface to investigate , a massive Horax creature attacks them , quickly decimating their squad of clone troopers . Despite Kenobi ' s warning , Skywalker kills the Horax single - handed . In the wake of the Horax ' s death , a tribe of Nelvaanians suddenly appears , with a young male at the forefront who is very angry at Skywalker ' s actions . Behind the scenes . The scene in which Anakin Skywalker returns to Padmé Amidala shows the outside of a building at night , and suddenly a single light goes out , strongly implying that the two slept together . As result of this , many fans have speculated that this was when Luke Skywalker and Leia Organa were conceived . This subject was supported by comments on the DVD commentary . Grievous uses K ' Kruhk ' s lightsaber to fight Dooku as the spikes are visible when he puts it back in his belt . Although it is not seen in this episode how Anakin received his scar , it was revealed prior to this episode ' s airing that the scar was the result of a rematch with Asajj Ventress on Coruscant . Another aspect is the the Clone Wars 3D series depicts the scar on Anakin ' s face far earlier on so Padme would have know about it for the better part of a year . The line said by Obi - Wan in this episode , " " My , what an incredible smell you ' ve discovered ! " " is an homage to Han Solo ' s similar line in . Likewise , " " There " are " alternatives to fighting " " is an homage to his own line in the film as the " Millennium Falcon " is being tractored into the Death Star . The rainy Separatist planet the Third Systems Army lays siege to has not yet been named , as well as several other planets in the same episode . Some presumed it to be Cato Neimoidia , although this is incorrect .
