I was just writing a fan fiction for RWBY, and I kind of ended up writing a theory from the back of my head regarding why Qrow said one look could "strike a Grimm down" (i.e. kill it), yet Ruby, when first unleashing her power, merely froze the Dragon.

Here's the theory: the energy released from a Warrior's eyes is a manifestation of all their positive emotions, discharged in two simultaneous beams of immense power. However, Ruby, having just witnessed the death of a good friend of hers, was overcome by incredible levels of grief, enough to drown out most of her positive emotions and in the process partially negate the effects of her power, just enough to petrify the Dragon as opposed to completely killing it.

Any feedback on this hypothesis, alternate theories, or noted flaws in my theory?
