Morag Macdougal had noticed Daphne was one of the few - if only - Slytherins in her Arithmancy class. Actually, there didn't seem to be that many people at all. She was surprised to see Michael Corner in there. Mistake in scheduling, probably. Morag just knew SHE would not help Michael when he inevitable took to slacking in studies for something like girls or Quidditch.
As she was walking toward the courtyard, in her own head about the assorted students in her class, she noticed Daphne sitting on the bench. Maybe it was time to make a friend in a class that had so few other options. She straightened her posture, unsure of what exactly to expect from this interaction.
Morag paused before Daphne. "Daphne," she greeted the girl. "I noticed you also chose Arithmancy this year. I just want to say that if there ever comes a time when we're grouped up, I think it'd be best for committed students to work together." Yes, that sounded official enough. Not too desperate, not too condescending.
