Clue was curious too, but certainly not socially inclined to suggest that they go searching for anomalies together. For together was not a concept the strange Slytherin was familiar with.

His eyes darted back to the fox as suddenly the little creature returned to full speed. But it seemed comfortable with both boys in the vicinity, so simply shook its head as if to dislodge some confusion, then sniffed around at some bluebells.

Clue straightened up to his full (puny) height, then made to walk in the direction of the castle to chase his curiosity. Whether or not Selwyn joined him was not his business, but the fact that Clue wasn't actively avoiding him was perhaps the greatest compliment he could give the Ravenclaw.
