Phial of potion in hand, Gabriella poked her head outside the office door and glanced towards the Ravenclaw girl and the Trigwell boy. "Mr. Trigwell, your potion," she said, holding up the second dose of the potion she'd been giving him in order to treat his amnesia. "With this dose, your memories should start returning a little more often now. You should notice a big difference within a week or two." She uncorked the phial and passed it to Rex. "Drink up now. You'll feel much better soon," she added. "Oh, and I do appreciate you...and your friends...remembering this appointment."

While she waited for Rex to take the dose, she glanced towards the Ravenclaw girl who'd been waiting outside for quite some time. "Please come in. Miss Zhang and I are just chatting, and we'd love for you to join us," she said. She nodded for the Ravenclaw girl to enter the office.

"Now Mr. Trigwell, as soon as you've drunk that, you may go. Just remember to return in one week for your third and final dose," she reminded him.
