Siobhan coughed slightly as she sat her bag down, displacing some of the dust from the room into the air. "At least he can't make us clean cauldrons? I heard he used to do that for the Gryffindors who annoyed him." She continued, more seriously, "I don't know... doesn't he seem [i]strange[/i] to you?"

She could have sworn Snape didn't look angry or upset at them fighting, only... melancholic.
