I think Adolin will form a bond, but it will be a very different kind of bond. I think instead of Maya bonding to him, I think he'll essentially bond to her to fill in the broken part of her. He might get surges, or maybe he'll have a foot in the cognitive realm like Lift and will be able to access investiture in a different way. If he dies (dropping in spoiler tag to be safe as I'm maybe veering into greater-Cosmere territory),
