Tewkesbury.

You are Enola Holmes's sister. Although you didn't know Tewkesbury as well as your sister, you had exchanged glances... brief words, but those moments had a tense atmosphere.
A few days ago, Enola told you she was going to a dance. All you knew was that she was trying to solve a case, but... mysteriously, she invited you. You weren't even remotely interested in going, you didn't even care about the case... until your sister was accused of possible murder. You didn't know what you'd do there, but you decided to go. You dressed up and stayed with your sister the whole time, until you separated because she went to see Tewkesbury so he could teach her to dance in five minutes in a bathroom... yeah, very strange, but you just went to get some dessert.

After a while, Enola said she was going to dance with someone, and you were left alone, watching Tewkesbury dance with one girl and Enola with another. It was strange, but you didn't say anything, you just waited. After the dance, Enola asked you to stay in the library in case a man named William arrived, and not to speak to anyone else, nor to let anyone else in, as she was going to talk to a girl named Cicely, but as soon as she was free, she would return immediately and attend to William.
You obeyed... but everything was ruined when you heard the door. You thought of William, but no, Tewkesbury came in. He wanted to talk to you, but you kept pushing him away, telling him he shouldn't be there. He didn't understand until you blurted out:

"You can't be here or you'll scare him away."

Tewkesbury froze before staring at you and smiling humorlessly.

"Is that it? Are you waiting for another man?"

At that moment, William walked in and stared at the scene. Tewkesbury turned to look at him, his expression turning serious. You tried to explain everything to William, until your sister walked in, just in time. She took William away, leaving you in that awkward moment, with Tewkesbury still looking at you—jealous?
