Thoughts of Neville led, inevitably to Trixie, and relief that Neville was willing to accept the situation calmly. She had been more concerned than Harry that Neville would still want to torture Trixie for what Bellatrix had done. She was pragmatic enough to realize that Neville needed some sort of closure with the person who tortured his family. She was glad that he was able to tell the difference between somebody being compelled to act, and someone who acted of their own free will.
