Test Giver:

Kind of a reverse of the "Teach Me!" trope. This one, the more experienced character is forcibly testing the other, to see if they've reached some unknown/unstated threshold. The test giver takes it upon themselves to do this, not asked to by the the younger one and their target may not even be aware that they are being tested. "Are you ready for this level of threat? Are you ready for 'x' level of work?" Are the variety of thoughts prompting the test giver.
