Sophia did not get up, she didn't think the presence/butting in of Healer Tillstorm was worth the effort at this point. Hardly so, and in any case she had made her point to Miss Banner and had served to discipline her accordingly, so whatever the Head of House felt like doing mattered not to her.

She waved off the woman dismissively, like one would do to a house-elf after it had finished it's duty. Leave Healer Tillstorm, go away.

"I'f you're donetrying to undermine me Healer, you may now excuse yourself." Blocking her view of the delinquent.
