maybe, when luz and hunter had their truce to save the palisman from kikimora and he excitedly started talking about wild magic before he cuts himself off, the titan was watching him too. i mean why wouldnt he? he knew belos killed his brother in cold blood and made grimwalkers with his corpse, so maybe he knew that all the grimwalkers would eventually 'turn' on belos and did try to show them his glyphs after they left/fled/ tried to fight, but bc belos always got to them quickly the titan never had a chance to truly get them to realize the magic is right in front of them. maybe he also likes that luz not only taught the first real victim of Phillip how to use glyphs, but retaught the whole isles how to use glyphs (and then some! since all humans can use glyphs as long as theres a big enough titan around)
