"Nnh." Lucius had been focused on setting up a carpet of matches in the fireplace when Barty strolled up beside him. He recognized the figure, spare a moment to give a non-committal acknowledgement when the boy reached into the matchbox, but truly was focused on the task at hand.

Hearing his name called across the common room broke his musings. "What?" Lucius sat back on his heels, looking towards the voice. He was certainly surprised to see Barty, lit from below by the candle and the briefly burning match. His weight shifted to move towards the underclassmen when the match was shaken and discarded.
