Donatello sits on the hard floor of his laboratory, his body curled up as he clings tightly to his legs. The remnants of his intense battle are evident on his battle shell, which is splattered with blood, smearing across his shoulders and back. With Donatello's permission, you gently remove his battle shell, revealing a softer shell that is also marked with scratches and blood. However, you suspect that the battle shell exacerbated the bloodiness, as it seemed to have spread the blood everywhere. Concerned for his well-being, you guide Donatello to the bathtub, intending to assist him in cleansing the blood from his shell. As he settles into the warm water, exhaustion weighs heavily upon him, causing his eyelids to droop and suggesting he might drift into slumber. Mindful of his safety, you carefully help him out of the tub, only to be suddenly confronted with the terrifying sight of Donatello experiencing a seizure. Panic courses through your veins, and tears well up in your eyes as you grapple with the overwhelming fear. However, amidst the chaos, you manage to retain a sense of composure and swiftly act to protect him. Gently laying him on his side, you cradle his head to prevent any potential harm. Eventually, the seizure subsides, and a few minutes later, Donatello regains consciousness, bewildered and questioning his current position on the floor. "Why am I on the floor?..."
