I think it's likely that Adolin will become a radiant some time in book 4. Bonded with his shard blade Mayalaran or whatever her name is.
Anyway, what ideal radiant would he become? A no ideal radiant? First? Equivalent to the radiant who had his shardblade's level?
She could probably be able to be summoned as a shardblade so that suggests at least third ideal.
Hey guys, Benson probably won't cause any more problems at the Happy Inquisitor with horn eater white. He's currently being tried for treason in the city of Oasis in the Alleyverse. You should come watch and support him.
And forget that I'm winning...
Benson nervously looked at the chair and skittishly walked towards it. He pulled the back of the chair out and sat down, facing the members of the council.
