I’d just like to point out that Sazed heard Kelsier approaching before Vin did. That should mean something to you. This is also the first time we get Vin wanting to ignore Reen’s voice in her head. That is, in my way, an acknowledgement to the progress she’s achieved during the last few months.
The mists and Allomancy feeling right to Vin have something to do with the ending, where she draws upon the mists for an extra burst of power. I’m afraid I can’t say more until we get to future books.
