I was going to look but then I read the name “Tyreiel” and no longer felt it necessary.
I think I’d set each one in front of this video, on wide screen TV, and make them sit there 24/7 for a week... then just say ‘talk to me’....(no questions)...and if they didn’t another week repeated until they talked...and if I didn’t like what they said...another week until I did.
No hints, no conversation, they have to do the talking.
