Agreed also highly likely.
But when I consider:
- the mention of how fast Urek climbed (yes, it's a kinder, gentler tower... But then why bother to mention it pointedly?)
- the mention of his data being unable to be contained on data floor, while Zahard's could (this one speaks for itself, but was of course pre king-contract. Again though, why was this mentioned?)
- Garam's request. Garam is in a unique position - she's a princess, got the tea from the strongest princess, has Arlen's pocket, and just overall seems to be knowledgeable about things esoteric to the tower. She doesn't strike me as naive, stupid, or foolish. Yet she asks for Urek specifically (knowing he's an irregular thus at least capable on paper) to do the dead. Does this confirm anything? Of course not but circumstantially lends more credit combined with other reasons to think there's probably a slight edge.
So, at least equal, maybe even stronger.
IMO.
