After dramatically passing out, Anakin is carried back to the ship by Obi-Wan and the clone troopers. There, they try and figure out what's causing him to breath so erratically as well as what's causing his eyes to bleed.
While the medics fuss about, Obi-Wan can't help but sit there in stunned shock, replaying the day's events in his mind over and over again. He knew Anakin had been behaving rather odd lately, acting almost like an entirely different person in some occasions, but he had simply assumed it was the result of the increasing stress of the war.
The battles had taken a rather brutal turn as of late and even Obi-Wan was starting to feel strained, so Anakin acting off kilter was understandable, but falling to the Darkside? Obi-Wan couldn't believe it. Even though he felt that oppressive darkness strangle him, even though he saw volcanic gold eyes looking back instead of blue, he still felt Anakin.
Most of all, all Obi-Wan could feel was his pain.
Especially right now. It wasn't even the physical pain that was troubling Obi-Wan, it was mental one. Anakin had tried to block their bond earlier, but the barrier he had put up was now crumbling, allowing Obi-Wan to peek through and see what was causing Anakin so much mental anguish.
What he did not expect was to suddenly pass out as his mental consciousness was ripped out him and shoved straight into Anakin's vision/dream.
It takes Obi-Wan a minute to adjust, he's stunned by how clear and vivid this vision is playing out around him. He's on some sort of Starship deck, one that he's never seen before, and standing right next to him is a tall masked figure dressed in black. The only sound that can be heard from them is the haunting echo of a strained respirator
It's Anakin. Obi-Wan has no idea how he knows this, he just does. He tries to say something but no matter how hard he yells, he can't make a sound. Anakin doesn't seem to be able to see him either and anytime he tries to touch something, he just phases right though it, like a ghost.
So he does the only thing he can do, watch and try and figure out what is going on. What plays out it is a typical day for Darth Vader, force choking position hungry admiral, interrogating rebel spies, and lastly, receiving a call from Sideous, the Lord of the Empire.
Obi-Wan cannot see the shadowed Sith Lord, but he can still feel the darkness pressing down on him like a physical weight. Even as Anakin answers his master faithfully, he sounds so hollow, barely able to hide the anger and resentment he clearly feels towards his teacher.
Then as Vader goes to meditate, both Obi-Wan and Anakin wake up at the same time.
Both of them are gasping for breath as they are violently brought back into reality. Obi-Wan cannot take his eyes off Anakin, who's gold eyes are rimmed with angry tears. "You saw it all, didn't you?" Anakin hisses out. "I couldn't see you, but I could feel you. You were there."
Obi-Wan nods and takes big breath before he gently grabs Anakin's arms and gives him a pleading look. "Anakin please, please tell me what going on."
Tired and knowing the gig is up, Anakin spills his guts. He tells Obi-Wan about his dreams, about the monster called Darth Vader that lurks just underneath his skin, that he was destined to become the boogeyman they all feared.
"I think...that you should kill me." Anakin feels utterly defeated when he says this to Obi-Wan at the end of his explanation. He can't see a way out of this, he's doomed. What he does not expect to feel is the hot surge of anger that explodes out of Obi-Wan when he says this aloud.
"Don't you EVER ask me to do that! I will do anything for you Anakin Skywalker, but not that! Never that!" Obi-Wan vehemently declares, much to Anakin's shock and wonderment.
After a small talk the two agree to keep this between them and not tell anyone, not even the Council. Anakin also gives Obi-Wan permission to view his dreams with him from now on, in hopes the other may uncover a clue on how to stop all of this.
For the first time in months, Anakin feels a faint spark of hope.
