Trying to read off the intended solution to Yog-Sothoth's puzzle from inside the dreamworld culture that Yog-Sothoth invented is definitely a good start. Dath ilan is pleased to see that Esta has been paying attention to all the thoughts he's been made to think, and maybe even absorbed some of the rhythm there! Good to see that fancy headband isn't completely for show if Esta at any point in his life tries to use it for something other than extra spells and channels!
Lecturing a dath ilani subordinate doesn't quite feel to dath ilan like the right frame, here, especially for a mind of Esta's capabilities considered realistically.
But you could be trying to learn-through-teaching of a fellow student! One who was, say, twelve.
