Ewart Fraser might be a possibility for a more chipper friend! He was also a Ravenclaw, although too much older for them to really have known each other at school, but they could still be more recent Ministry pals?

Savino Zabini is, as always, interested in any and all Seers so would definitely approach him if he'd heard rumours of that, and/or could come poking, probably unsuccessfully, at the Dept of Mysteries. xD
