Slowly the group of four former Admirals began to grow concerned. Uhura was the most concerned regarding Jim's health. She noticed he put a hand on the side of his leg when he walked. Chekov noticed that he preferred to rub it and sit down more often. Sulu noticed how less the man was walking. Spock, however, was enjoying the time he had with Jim which involved putting a large puzzle together. And Scotty noticed the man wasn't as talkative. Jim likely dismissed the pain as being part of his old body not being resilient on working with machinery but the crew knew better. So it was decided that Sulu go to sick bay armed with knowledge that not everyone knew.
"Doctor Chase?" Sulu entered Sick Bay with a concerned look on his face.
"Mr Sulu." Chase said, looking up from the pad. "What brings you here? You don't have a physical set for this week."
"It's about Jim." Sulu said.
"Hah, everyone is thrilled he can walk." Chase said.
"It is about his legs." Sulu said.
"It is a miracle they can work." Chase said.
"He is limping." Sulu said.
Chase shook his hand turning toward the man.
"Oh, that is part of the side effects." Chase said. "He is obliged to tell me if there is pain coming from the device."
"Two weeks ago he was not limping," Sulu said. "If Bones were here there is a good chance he will say something is wrong and you are a big fat liar." Chase looked up from the pad. "That isn't a model on the market. Isn't it? It is a prototype. I seen something like it." His hands were in fists. "Tell Jim what the hell you put into his body or I will."
"You don't know what it is." Chase said.
"I saw it before. And I saw it end terribly for the recipient. I don't like history repeating in my eyes, again." Sulu said. "I am willing to report you to the board for taking prototypes from the medical facility on Pailon II. I know that for a fact Star Fleet banned use of it. I was part of that meeting, Doctor."
"Medical Admirals say it's safe." Chase said.
"Was Doctor McCoy part of that group?" Sulu asked, only to be met with "I do not know if he was part of the group." He could feel his blood boiling. "How long ago was that?"
Chase frowned looking at the older man.
"Five years ago." Chase said.
"Tell him." Sulu said.
"I will." Chase said.
"I am counting on that." Sulu said, then he walked out of the room leaving Chase to sulk in his chair.
Chase never did tell Jim the risks.
