It's definitely a good theory, but I can't be sure. I would say if it was, it's powers were enhanced by the magical staff, allowing him to shoot energy, and he touched people's hearts because he thought it added a dramatic affect (c'mon that totally fits Loki). If not, it was probably just a fragment of the Tesseract.
