I had the raging tearful reaction too... Elend is one of my favorite characters of all time, along with Sam Gamgee and Faramir (he rather reminds me of Faramir, actually) in LotR, because he's just so GOOD. The only thing that kept me from throwing the book was that it belongs to my boyfriend (kinxer on 17th Shard!), who got me hooked on Sanderson in the first place, and I didn't want to mess up his book.
I just really wanted them to have children. Maybe I can just pretend they were able to do so in the afterlife somehow? Like how the Greek gods had children, since Vin at least was a god for a little while...
Also, we need a much larger fanbase here. I'm thinking couples' t-shirts and things for Sanderfans that relate to Vin and Elend. And mugs with quotes. And lots of web graphics and things. And fanfic. Let's get to it!
