We don't need to plot now, you should probably get some rest. Plotting when tired (or upset for me) usually is something I regret and make a mess of. I'd say I can come up with 1-2 possible images for the student's human form. For all we know, he could target her already during the current week since he might sense she's a threat and want to eliminate her quickly. Then by the following Friday, she's finally at the point of killing herself. Then Kurama can sweep in and stop her, but still prompting the danger around them, as it's clearly not over.
