"Therapists," Al supplied and when that didn't get much response, he tried, "Psychiatrists. Um, mind healers, in a way." He shrugged. Problem or puzzle? Perhaps both. One could never tell with therapists. "It's a Muggle thing, or at least most of it is. Some of their research is scary, some - potentially useful but the majority - contradicts itself a lot." He glanced up at Caractacus and smiled like a firstie hoarding a secret stash of sweets under the bed.
"After my therapist was killed, I've kept her reference books. They're quite dry and yes, they do bring up a lot of questioning and discomfort."
Still, books!
Al blocked the immediate line of attack and eyed the piece with caution. He didn't like that rook there. Go back, rook. Stop being nosy.
