After the fourth time of this process, Draco had finally realized what she was doing. He couldn't hear her thoughts, as Harry was the only one he could easily communicate with. But he felt that she was training him to heal memories properly. When he worked with Joel, they were stumbling through it... guessing. He wasn't far off, but it had been a lot of trial and error. He grumbled, internally, and decided that he didn't see how this apparent do-gooder would or could hurt him. He dropped his walls.
Her shock at his sudden decision was apparent, but she sent reassuring feelings through the link before she came into his mind. They still couldn't speak, as trust was not that earned, but he let her look around like he let Joel. Her thoughts were pleasant and soothing, trying to ease his fear, though he wasn't easily assured. He felt that she wanted to see how he had learned. He obliged her and took her to those memories. She watched them with a mixture of awe and disgust. She tried to ease the tension, but he didn't let her emotions touch him that much.
After a few moments of attempting to calm him passed without much progress, she ended the spell, and they were back in his room. He eyed her warily, registering that Joel was shaking. They were in each other's minds for a long time. Obviously, Harry hadn't arrived, or he would have ended it.
She asked, "Draco, are you alright? You weren't responding."
He shrugged and grunted, "You saw the Dark Lord rooting through my head. Responding is a way to get killed. I know Occulmency, too, healer. You don't."
"I know enough to protect myself, but I never had to employ it like you did," she said, nodding. "Did you learn anything?"
"Some. Calm down, Joel. I'm fine," he said, meeting his eyes.
"Sorry... I just...."
"Draco and I were getting to know each other. I realize that you are still under healer's care, but when you've recovered... perhaps we could learn a few more things from each other?"
He gave her a look. "To what purpose?"
"Draco... let me explain to you that what we just did... is not common. I knew something was immediately different when I tested Joel for his license. I think... with your help... we can improve training and processes for mind healing."
Draco wasn't sure what she was saying and gave her a confused look.
"When you are released, I want you to come to the center, and we can develop a training program."
"Madam healer... I'm a former Death Eater who can't walk on my own and can't even produce enough magic to summon my remote," he muttered, glaring at the thing under his bed, again.
She nodded. "You didn't need magic or the ability to walk to do what we just did."
Draco sighed. He hated the feeling of being vulnerable, and being around strange, unfamiliar people was not something he wanted to do.
"It can just be you and I... until you're comfortable? I also can help you recover easier than Joel can."
"I trust, Joel," Draco said, flatly, and Joel blushed.
"I know, but he's inexperienced. We will, of course, build our own relationship. Eventually, I believe I will earn your trust as well."
Draco blinked, again, confused. "Are you offering me mind healing sessions or training sessions?"
"I'm offering you a job."
Draco leaned back and just said, "Huh."
The healer left about a half-hour later. He asked a few more questions, and she explained what she was offering. He would not immediately give her an answer and merely said that he would think about it. She left and Joel needed some extra reassurance that he was fine.
