[Oh!! Oliver!! His knight in shining armor, how can he ever thank you enou--

The nurse turns her gaze to this new interloper, her face just as incredulous as before.]

"Who are YOU?!"

[No. This won't do. Oliver already started the lie; Mettaton has to complete it.

He stares at the woman, aghast, as the patient in his arms slowly begins to calm. One hand now free, he can gesture at Oliver with all the shock of a seasoned professional.] First you have the nerve to bring up the death of my FAMILY, of my own BLOOD, and now you insult my HUSBAND?? Is there no heart in you?!

[The woman opens her mouth again, confused and not quite sure where any of this is going, but Mettaton speaks over her. There's no backing out now.] Did you really think I would leave him alone in all of this mess?! After what happened to my BROTHER?! I need you to leave. I need you to leave my sight this instant, Ms. Clark!!

[Her eyes flicker from Mettaton to Oliver. She hasn't grabbed a coworker, but the thought of doing so still obviously lingers in her mind.

Finally...]

"...My name isn't Ms. Clark."
