Well, it would be disappointing if it didn't. What with the constant changing of carrier, there's room for creativity here too.
I'm hoping for something different this time, like finding out that Umbra is carried by some NPC you already know and like, and it's driving him/her slowly crazy, and you discover why during a quest (maybe given by concerned relatives, I don't know). And anyway, you're left with the option to either leave him/her be, or kill him/her, both choices having serious consequences. Umm, anyway, a plot twist like that.
Plus the sword should drive you nuts too, if you choose to carry it. Like having no longer the option to solve conflicts by talking nor sneaking out. Or having to kill people or the sword starts to leech on your abilities.
