"I woke up to my knee feeling numb," Katya replied. "And now I can feel a panic attack coming on."<br/><br/>"I'm sure it's nothing," he said, taking a walkie-talkie from his belt. "Isaac, have you got those painkillers yet?"<br/><br/>"I'm on my way back," came Isaac's response. "I'm going as quick as possible."<br/><br/>"So what's going on?" Mark said, frowning as he touched the knee, prodding it. "Kat, can you feel this?" She shook her head, concern written across Mark's face at her response. "Kat, do you mind if I just borrow my sister for a moment?" He took Geri to one side, far enough away Katya couldn't hear. "I want to get Isaac's second opinion but...this may or may not be something to worry about. It could be the nanomachines are effecting her nerves while repairing the damage. The other possibility..." he put his hand over his eyes, trying to calm himself. "Geri...if this goes wrong, she may need a wheelchair for the rest of her life, I've not told Kat because she's worried enough and I hoped beyond hope I was worrying about nothing."
