For a moment Cass wondered if he should tell Harry everything or not. On the one hand, he didn't want to do anything that could upset Percy, and telling another person might very well do that. On the other, he didn't want to force Pansy to keep lying.
He settled on a compromise. 'I'm quite fine with not shutting her up that way any more,' he said with a grin. 'I have someone of my own to shut up that way these days. Don't ask who, because I won't tell - yet. But I will, soon.' He smiled. 'It is a shame on that possibility of a threesome though,' he joked, winking.
He paused for a moment, then deciding that there were some things he could tell him, that he might need to know.
'There is something I do want to tell you though,' he said slowly, waiting for Harry's reaction before going on.
