He first hooked Obi-Wan up to the life sensors in the med-bay. Then he went to the cockpit and activated the comlink, setting it to the secret Jedi frequency.
"This is Padawan Anakin Skywalker. My master is down and I don't know what is wrong. I need assistance right away! Repeat, this is Anakin -"
"Ani?" a female voice asked over the comm.
"Yes!" Anakin said, relieved to have found someone. He recognized the voice, but wasn't sure of who it was.
"What's wrong with Obi-Wan?"
"Who is this?" Anakin asked instead of answering.
"This is Siri. Now what's wrong with Obi-Wan?'
Siri! She was Obi-Wan's friend. "He's not conscious, but I can't feel him. I mean, his body's there, but his spirit isn't."
Siri was quiet for a moment. "Give me you coordinates." Anakin complied and fed the coordinates to her ship, wherever she was. He waited a minute while she read over them. "Good. You're only a small jump away. Ferus! Put these coordinates in and punch it! We have an emergency!" she told her Padawan, Ferus Olin, who was out of Anakin's earshot. "We'll be there as soon as we can. Try to reserve a port next to you. Siri out." After that, Anakin could get no more from her.
Doing as she asked, Anakin ran down the ship's ramp to the owner of the spaceport. "Excuse me, sir!" he shouted over the continuous whine of engines. The Dresselian turned to face the small human running towards him. "Could you please keep the port next to my ship open?"
The Dresselian stared at him for a moment with his wrinkled face, then turned his attention to the datapad in his hand. "No one's scheduled to land in it. But why do you want it?"
"I have some friends who are coming and they wanted to be right by us. I'm sure they'll pay for the space." Anakin shouted.
The owner nodded. "I'll keep it open. What is their ship's name?"
Anakin paused. He didn't think to ask Siri what the name was. "I don't know. But her name is Siri and she's with a boy named Ferus Olin."
"You don't know her last name?"
"No. I don't even know if she has one!"
"I will make sure she gets it, but she will still have to pay docking fees. When will they be here?"
"I'm not sure, but sometime before morning."
"Ok, I'll keep it open." the Dresselian repeated before walking back into his office. When Anakin returned to his ship, he was suddenly frightened by the quiet and stillness. He went into the med bay, but Obi-Wan was still the same as when he had left him. Anakin returned to the cockpit and plopped down in the pilot's seat. It was too quiet for him. Normally Obi-Wan would either be talking with him, or practicing with his lightsaber and a droid in the back. Now, there was nothing. He looked at the copilot's seat and could almost see Obi-Wan sitting in it, wearing the impish grin that came less and less as time went by.
This is what life would be like if he died, Anakin suddenly thought. I would forever see him, but he wouldn't be there. The Temple would try to give me a new Master, but I wouldn't allow it. I would leave the Order and forever be a drifter, no family and friends. Anakin glanced back into the still med bay. He'd better not die. Please don't die, Obi-Wan. You're all I have.
