Sneaking into the facility where Anakin was held was tricky. There was dry, clear terrain, except for a few natural rock columns. The trees had unfortunately ended some ways back, the master and droid had left the speeder hidden there. As a jedi, Obi-Wan could easily get past most guards without notice. However Artoo was rather hard to hide. Artoo bleeped uncertainly as Obi-Wan dirtied up the droid's exterior with grease and dirt. "Look at it this way, I'm quite sure that Anakin will give you a thorough cleaning afterward."
The droid turned his dome and blathered at him. The translation lit up the datapad. "Shouldn't the one who made me wear this filth clean it off?"
Kenobi sighed. "I'm sure he would do a much better job. For now, it's all we have for camouflage."
Artoo approached rumbling over rough but cleared terrain. Obi-Wan, used the Force to make himself virtually invisible. Two guard droids wheeled back and forth by the main entrance. A clone trooper - another merc type - appeared and disappeared inside the door. Obi-Wan timed his approach between the droids rolling back and forth and used the Force to make a clatter in the wrong direction. The two rolled and in that direction. Obi-Wan slipped in and subdued the guard, relieved to note there was only the one. "Ah. Here." He tapped a few commands, sending the guard droids to investigate movement in the other direction. His eyes lit on a weapons closet and he opened the door. "Aha." He came out with both Anakin and Ahsoka's lightsabers.
Artoo rolled in the door, plugged hastily into the computer. He squealed in alarm, rerouting a speaker and a voice boomed out.
"I guess your padawan wasn't so important after all."
"Can you find them on the ..."
The holos displays lit up.
"...the security cams. Oh no!"
Ahsoka was struggling violently and Kenobi could feel her pain surge in the Force. He could also feel Anakin's building fury, along with the odd buzz he'd felt before. He quickly located him in the display. Two boys...a clone of himself and Qui-Gon...so strange, them being the same age...were alongside. They crouched, looked up with snarls and clenched fists. But they weren't lashing out. They couldn't see anyone to aim at.
"Perhaps if you help me subdue the our young templates and return for testing, I'll stop hurting her."
The boys looked at Anakin, wary. Anakin bolted away, startling the boys, who followed after glancing at each other. Obi-Wan spun away. "Can we get to Ahsoka?"
Artoo squealed and scooted down a corridor, hopefully to Ahsoka. Yes, definitely. Her pain reverberated in the Force. He felt her struggling to calm herself even from here. Anakin should be proud of her.
"Artoo wait!" The droid hurried around a corner, squealed and zoomed back toward him. Obi-Wan's lightsaber flared blue and he jumped out, deflecting the red blaster bolts. The three merc clones fell, hit by their own shots. He deactivated his weapon. It had all happened in seconds. Artoo peered around the corner, then scooted back out and rolled quickly down a ramp. They hurried down a corridor with multiple doors. The concerned jedi master checked for living presences, but if there were droids in there he wouldn't know. He could easily end up in a trap, weapons before and behind. But he hurried after Artoo, nonetheless. It was almost as bad as trying to keep up with former padawan. Worse perhaps. At least he could feel Anakin in the force.
Artoo stopped beside a locked door, plugged in, tweeted and rotated his dome, looking at him. From what Kenobi had seen in the holo, the young padawan probably was being guarded by droids. Lightsaber ready, he nodded at the droid. The door opened and he rolled through the door. Two droidekas...it would be droidekas of course, instead of the easier battle droids...turned toward him. Ahsoka kept jerking, sparks slamming into her through the field. Lightsaber flashing, Kenobi kept on the move, trying to think of a way to defeat them. He reached out with the force, slammed his hand forward and the droids crashed into each other against the wall with the gesture. But they popped up almost instantly.
Artoo Detoo zoomed past, hitting the controls and shutting down the electricity. Ahsoka was snarling. "Artoo. Get me down!"
The droid complied immediately. The girl hit the ground on her feet, hand reached out and her saber leaped off Kenobi's belt. He paused long enough to hit the slave collar with his own blade. Fortunately, it popped loose instantly as her own green blade flared and she charged the droids, than bolted out the door. Obi-Wan followed. She'd vanished when he hit the corridor. He had no time to look, they were rolling too close behind him. He spun as the nearer one unfolded, slashing before it's shield could go all the way up. The other one was still in mid roll when Ahsoka's green blade slashed it from one of the side rooms.
"For a moment there I thought I'd lost you again."
"Sorry Master Kenobi. I had to deal with a few clankers in the other room." She scowled, spinning back up the corridor. "Now. Let's find the sleemo behind this place."
"Did you backtrack the signal from our broadcaster?" He asked Artoo.
The droid squealed and flashed a holo schematic of the place.
They backtracked up the corridor, running full tilt. In the distance, blaster fire was getting closer, along with an odd hiss - hiss - hiss sound. They came into a corridor where Anakin spun and kicked, battling the droids and merc troops. He and the boys were far outnumbered. Whatever Anakin died, the boys tried to imitate. They seemed in tune with each other and with him and had some success. The odd hiss, hiss sound was coming from some odd, large droids firing darts.
With a yell, Ahsoka leaped into battle. Without missing a stride, Anakin called his own lightsaber to hand from Kenobi's belt and started junking droids. One boy, Qui-Gon, somersaulted, grabbed one odd droid, swung it around and used it's own weapons to dart the soldiers. The other boy landed mid leap. His eyes were suddenly huge, blue, and staring at Obi-Wan. He stared back for a fraction of a second. Then he joined the battle discipline and habit overriding the uncomfortable buzzing.
Then the battle was over. They were breathing a bit hard. "I'd ask for introductions. But I already know who you are." Obi-Wan said.
"I'm you! I mean..." the boy looked confused. "If you're Obi-Wan," he said, "he said I'm you..." The boy waved at Anakin.
"Not to be rude. But let's sort it out after we catch these guys." Anakin said fiercely. He looked around. "Ahsoka?"
Her footsteps thudded up the corridor, clearly not waiting for them.
Anakin hurried after her. Obi-Wan hesitated when the boys followed but Anakin murmured sidelong, "He's you. Would you miss out on this?"
"Ah. No. Good point. He's every reason to be angry and no training to tell him how to deal with it."
