Julian watched her with a mixture of emotions on his expression. Had anyone been paying attention, they might have thought he was doing this to her. Which was only half true. He had a look of mild curiosity, wondering exactly what it was she was seeing. Julian only gave her a push in the direction, he didn't plant the images in her head. And while he was quite pleased with himself, and obviously so, he still felt something like pity, or maybe it was shame. Perhaps it was love for his sister who was obviously going through so much right now. Although you'd never get him to admit that and to suggest it would mean immediate death.
It was quite obvious when Parker came out of this one. Julian reached forward instinctively, grabbing her as she fell so she wouldn't hit her head. His free hand drew the necklace to him telekenetically, tucking it in his pocket before she could notice it. His face showed obvious concern and worry, which his was actually feeling, just not as severely or purely as a stranger should have. "Oh my God! Are you okay? I'm so sorry! I didn't mean to bump you! You're not hurt are you?" Concerned citizen response number one, take two.
