No. Because that does not solve the yogurt cup issue, or the vomit. Not to mention the bloody prints. [he tilts his head at her]

Perhaps the original intent was poison. Did you give her the poisoned yogurt, then when she realized what you'd done, accidentally activated her power, which neither of you suspected, and caught you in the blast? Is that why you had to stumble out to the bathroom? Because the shrapnel of her exploded body caught you in the blast--resulting in unsuspected blood--but the gruesome sight also caused you to vomit? Therefore, you had to get rid of the blood and the vomit on your breath.
